Love takes time, dedication, and passion. Now, more than ever, society is mirroring those efforts in sourcing the perfect engagement ring for their significant other. It’s a visual celebration of the journey that led one to their soulmate. So, which engagement ring is right for you and your partner?

Trends come and go, so it’s important to remember that there’s no rulebook when it comes to engagement rings. Cut, color, clarity, and carat are highly important, but one factor should be decided on first – the overall design. As connoisseurs of exquisite and rare gems at Dehres, it’s only natural for our favorite engagement ring designs to showcase the gems that inhabit them. We recommend choosing sophisticated, timeless designs such as solitaire, trilogy, and halo engagement rings.

Most recently, many are investing in diamonds in the larger 3 to 4ct range for their partner, making a bold declaration of their love. The request for intricate design elements in the settings of an engagement is also at an all-time high. This is most frequently featured in the form of micro pavé diamonds intricately set into the structure of the ring.

Solitaire engagement rings lend themselves to an elegant simplicity that no other style can offer. They also allow you to dedicate your investment to a single feature stone, encapsulated in either 18kt gold or platinum.

However, gone are the days of the round brilliant cut diamond being the most popular shape for this style of ring. We’re seeing many more requests for fancy cut diamonds, such as oval, cushion cut, and emerald cut diamonds. Quite frequently, they’re set with shoulder stones especially when the center stone is under 5 cts, which make the main stone appear larger and provide more diamond coverage across the span of the ring.

Another popular option is mounting the diamond in an East-West setting; a beautiful modern adaptation of a classic design, where the orientation of the stone allows for the longer side of the stone to be set parallel to the ring band.

Halo rings exude a femininity that is glamorous yet delicate. A center stage is created by surrounding a larger gem with a multitude of intricate smaller stones in the form of a halo. These rings are exceptionally versatile and are well suited to customization. The carat size of the center stone is a big factor here, and currently, we’re seeing a lot of investment in the 3ct plus range. Our halo rings can feature a colored gem; however, they are equally stunning in an all-white diamond arrangement.

There is something exceptionally romantic about choosing a colored gem for an engagement ring. It takes an intimate knowledge of your loved one’s style. Sapphires are incredibly popular at the moment and are an outstanding engagement ring choice because of their durability. They are found in a myriad of colors, and we frequently encounter rarer varieties and origins here at Dehres. Perhaps you are drawn to the warm pink-orange tones of a Padparadscha, or the rich blues of a Kashmir, or maybe it’s not a sapphire but a luscious red Burmese ruby or even a colored diamond that will be the perfect match for your ring.


At Dehres, we have an exquisite collection of bridal jewelry to complement our beautiful engagement rings. Our pieces have all been created by a team with decades of knowledge and experience and are symbols of everlasting elegance and unity. We would be delighted to assist you in this special chapter of your journey and help you choose an engagement ring that is perfectly yours.

Natural Green Diamonds – A rare commodity in a diverse jewelry culture?

20.04.2023 | Natural Green Diamonds | Diamonds

Green diamonds are among the rarest colored diamonds in the world. Their color evokes a sense of growth and vitality. The true brilliance and scintillation that only a diamond can possess are simply mesmerizing when paired with such an exceptional hue. Fancy vivid green diamonds rival the finest blue and pink diamonds, and when paired with their scarcity, it’s no wonder there has been a surge in their value in recent years. In reality, all colored diamonds only represent a mere 0.01% of the world’s diamond yield. Green diamonds make up just a fraction of that percentage.


When Jennifer Lopez’s engagement and wedding to Ben Affleck recently hit the headlines, a green diamond was splashed all over the tabloid pages worldwide. The flashy stone took the world by storm, showcasing green diamonds in the public domain.

The most beautiful green diamonds hail from Brazil, South Africa, Venezuela, and Guyana. The green is caused by a displacement of carbon atoms in the structure of the diamond crystal at the time of its conception, millions of years prior to its mining and discovery. The color and structure of the diamond are considered stable, and the color is permanent. The color, however, can be only surface-deep, depending on the type of diamond. The rarest of green diamonds have a cohesive green body color which will not be affected by the fashioning of the diamond crystal into a cut gem.

Due to their scarcity and the genuine possibility of treatment, green diamonds are typically regarded with suspicion and examined carefully in gemological laboratories before heading into the diamond market. Beyond that, green diamonds, like all other colored diamonds, can be graded using the current GIA Colored Diamond Grading standard to describe their color. The grades are as follows: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Dark, Fancy Intense, Fancy Deep, and Fancy Vivid. The majority of colored diamonds fall into the Faint to Fancy range. Dehres is proud to offer Fancy and Fancy Intense Green diamonds among our collection.


Delving further into the color range, green, blue, and pink diamonds in the Fancy Intense grade command prices in the hundreds of thousands per carat. While they are highly valuable, the highest of accolades is bestowed upon the Fancy Vivid grade.

This is where the key defining factor between these three colors comes into play. The Fancy Vivid green diamond is the rarest of the three, and its rarity increases its desirability. With so few Fancy Vivid green diamonds in circulation, they command prices well into the millions per carat, reserving them for the most astute collectors and connoisseurs who would like to diversify their collections.

Such is the case with the largest Fancy Vivid green that has been publicly recorded. The Aurora green diamond was a stunning 5.03ct, Cut-Cornered Rectangular Modified Brilliant Cut with VS2 clarity. It was set into a ring and sold for 16.8 million by Christie’s in Hong Kong back in 2016. The per carat price of this diamond is 3,330,000, and it is currently the most valuable Fancy Vivid green diamond on record. The record was previously held by a 2.54 carat Fancy Vivid Green VS1 diamond that was sold by Sotheby’s back in 2009 for approximately $1.22 million per carat, after the financial meltdown when diamond prices were low.

In comparison, last year, we had, among our extensive range of rare gems and diamonds, a 1.10ct cushion cut Fancy Vivid green diamond, which sold for 1.3 million per carat.

So, is the green diamond worthy of owning? The above anecdotes indicate that, yes, that is indeed the case. Mr. Zion believes, “If present trends continue, I definitely anticipate the price of green diamonds to remain strong and potentially increase. It’s extremely hard to find a nice vivid green.”

Fancy Vivid diamonds are currently so rare that Dehres doesn’t have one available in our extensive collection, though the hunt is on to source another magnificent piece of gemological mastery.

17.03.2023 | Sapphires Beautifully Encapsulated | Precious Stones

Blue sapphires are among the most highly valued gemstones in the world – prized for their vibrant hue and associating the gemstone with royalty, wisdom and protection. Whether you’re a seasoned collector or simply curious about this beautiful gemstone, we reveal some of Dehres’ stunning blue sapphires in our latest blog.


Sapphires that originate from the Kashmir region are typically the rarest, most beautiful, and desirable of all sapphires. Their treasured beauty is due to unique needle-like⁠ inclusions known as rutile needles, giving Kashmir sapphires their⁠ distinct, velvety and sumptuous glow. Their beauty, combined with their rarity and allure mean that Kashmir sapphires command the steepest prices among all sapphires.

As certified by SSEF, GRS, and Gubelin, the above 3.08 carat Kashmir sapphire shows no indication of any heat treatment. ⁠


This 6.99 carat cushion cut unheated Kashmir sapphire of deep intense blue is elegantly framed by tapered baguette diamond side stones in a timeless ring of unrivalled beauty.⁠ ⁠

Aptly classified as ‘Royal Blue, the cushion cut Kashmir sapphire displays no indication of any heat treatment. The 7.52 carat stone’s velvety blue hue is truly one of a kind. ⁠


Burma is another important country of origin when it comes to sapphires. Known for their deep color saturation that often result in their being classified as ‘Royal Blue’, Burmese sapphires are, indeed, very special.

Weighing in at 15.48 carats, this Royal Blue cushion cut Burmese sapphire ring is truly a sight. The fact that it shows no indication of any heat or treatment makes this exceptionally clean and saturated sapphire even more remarkable. ⁠


Sri Lankan, also known as Ceylon, sapphires are prized for their bright medium to deep-tone blue color. Sapphires with such features are referred to as ‘Cornflower’ or ‘Royal’ blue, respectively. They are, both, extremely desirable with Royal Blue sapphires commanding steeper prices. With mines in Kashmir being shut and Burma focusing its mining efforts on Rubies, Sri Lanka has become a primary source for sapphires, today.

Among the rarest sapphires are those that display no sign of⁠ treatment to enhance its color, like the above unheated 20.44⁠ carat Sri Lankan sapphire. ⁠ ⁠Beautifully framed by two crescent diamonds side stones, its Cornflower hue is among the most sought-after of all the sapphire colors, and retains its luster in any light, further enhancing its appeal.⁠ ⁠

07.02.2023 | Symbolic Valentine’s Day Gifts | Diamonds | Trending | Blog

As Valentine’s Day approaches, we know many of you will be looking for deeply significant gifts. Jewelry is a popular choice, not just because of its aesthetic appeal but for its symbolism as well. In this blog post, we’ll introduce you to the symbolic meanings behind exquisite jewelry, to help you choose the perfect design for your special someone.


Featuring two exquisite stones, twin rings are representative of love and friendship. You’ll often see them incorporated into wedding rings to symbolize a couple’s commitment to one another. Given their nature, twin rings are super versatile and full of personality, as they can either be designed with identical stones, or stones that differ through color, shape, size, etc. Regardless, those stones will always complement each other, emphasizing the “2 of us” aspect of the ring’s design. Twin rings are a statement of the unbreakable bond that is unique to two souls in love.

These bracelets sport a uniform, simplistic, and clean look. The design incorporates minimalism to maximize its beauty and charm. Tennis bracelets are symbolic of feminine strength and grace; they reveal to the world that their wearer is strong-willed and determined. Given their seemingly ‘endless look, they’re also symbolic of everlasting love. They are the perfect gift for that confident, special someone.


Fun fact: Tennis bracelets earned their name after tennis player, Chris Evert, was spotted always wearing a diamond bracelet during matches. Thus, the media dubbed the jewelry the ‘tennis bracelet’. The bracelet gained worldwide fame when during one match, it came off and Evert immediately asked for the match to be stopped until it was found.

When shopping for diamonds, you may hear the terms brilliance, scintillation, and fire. Whilst these are highly important to understand when purchasing diamonds, oftentimes people are either confused by these terms, or completely unaware of them. In this post, we want to spell out what these terms mean so that you can be more informed when you’re looking to purchase diamonds.

Diamonds come in a wide array of colors and we at Dehres are proud to feature a spectacular range of fancy colored jewelry in our collection, including diamonds that are fancy pink, blue, green, yellow, and more. There are also colorless diamonds of course, which are more familiar to the world. How these diamonds reflect light back and sparkle will have an impact on their overall appeal and that is where fire, scintillation, and brilliance come in.

Fire in a diamond refers to the dispersion of light. Essentially, when light enters a diamond, it splits into several other colors. If you were to visit a jewelry store and look at a diamond under the store’s lighting, you might see lots of beautiful rainbow colors looking back at you. That’s fire! It’s important to note that the size of the facets featured in diamonds will impact the size of the fire. Larger facets will mean larger fire. The cut of a diamond will also play a significant role in its fire, scintillation, and brilliance.

2.00+ ct Radiant Fancy Vivid Orange S12 Diamond (C289035)

When you move a diamond in different directions, such as by rotating it, the fire will move (or ‘dance’) around. This movement is known as scintillation. If a diamond has a higher number of facets, it will usually mean higher scintillation. However, if there are more facets, the fire will be smaller as the facets themselves will be smaller.

Brilliance and fire can be a bit confusing to understand due to the similarities in viewing both. To see brilliance, however, you need to look at a diamond under white light to observe its levels of brightness and contrast. To put it very simply, fire refers to colored flashes, and brilliance refers to white flashes that are contrasted by the darker tones within a diamond. What are tones? Think of 3 colors: white, black, and grey. When you’re looking at a diamond’s brilliance, you may see tones of grey, for example. This is important! The intensity of tones within a diamond need to be balanced and well distributed, as this will help highlight a diamond’s brilliance more. If you only see grey or black tones, the stone is too dark. If you only see white, the stone will be unappealing and dull. Pattern scintillation is important to note as well, as brilliance needs to be judged when looking at a diamond from different angles, not just from the top. If you notice high brilliance whilst observing a diamond in various directions, it indicates good pattern scintillation.


This is where personal preference comes into play. Some people may prefer higher scintillation due to the attractiveness of the movement of color, whereas others might want fire featured in a diamond more because of the eye-catching nature of the colors on display. It’s always best to see diamonds in person so that you can determine for yourself what it is you find most appealing. You are more than welcome to visit us and learn more about fire, scintillation, and brilliance in a diamond, as well as to determine your preferences. Feel free to reach out to us and make an appointment. We would love to speak with you!

Quintessentially Dehres

15.09.2022 | A Legacy of Timeless Jewels | Diamonds & Gemstones | Blog

The House of Dehres is a widely recognized enterprise renowned in the world of diamond, gems, and high jewelry. But it is also so much more than that.


Starting with a humble beginning, our founders Ephraim and Hannah Zion created not only a high jewelry house but also a home* where their finest goods reside and esteemed clients can visit and view them in a warm and friendly environment.

While the foundation of our company is based on Trust, Integrity, Passion, and Commitment, the core of our business are our opulent, ‘one-of-a-kind’ pieces. Our mission remains: to elicit joy and awe through beautiful, rare, and artistic jewelry creations.

In this blog, we will delve into the Zion Family Favorites and what sets these chosen pieces apart.


More than just our founder, Ephraim is an iconic figure and leader in the world of diamonds, precious stones, and fine jewelry. Beginning his career as a diamond cutter at the age of 14, it is safe to say that some of the world’s rarest and outstanding diamonds and gems have passed through his hands.

However, when asked about his favorite, or rather, the most impressive stone he has called his own, his response was almost instant; a 5.18 carat Oval Paraiba Tourmaline. He describes its color as so deep and saturated that to an untrained eye, it could be mistaken for a Sapphire. “What makes this gem so spectacular is that it’s flawless, devoid of any inclusions despite being totally unheated.”

“You really can’t find anything like it.” This is because the Batalha Mine in Paraiba, Brazil has been shut for the passed few years and despite great efforts, no license has been granted to continue mining it.

Hannah is the matriarch of the House and we were extremely curious to discover what her selected favorite would be. A lover of fine details and artistic jewelry creations, we were surprised to discover that her favorite item was also a loose stone; a 10.12 carat Marquise Zimmi Yellow.


Cut down from 24 carat rough, it was discovered in the Zimmi Mine in Sierra Leone. When asked what attracts her to this specific stone, Hannah told us that she’d “never come across a natural stone with a color as saturated; it’s like a fiery sun”. In fact, the color is so mesmerizing and intense that other experts in the industry often question whether its’ artificial. Ephraim added that “in all [his] 62 years in the diamond and gem industry, [he’s] never seen anything quite like it.”

The House has one item that we just knew would be a favorite; it was just a question of who would pick it and much to our surprise, it was loose stone lover, Ronen.

Aptly named ‘The Masterpiece’, the selected necklace and features 77 Afghani Emerald Polished Beads and a 75.51 carat Sugarloaf Cabochon pendant. Regarding the beaded necklace, Ronen shares his doubts at ever sourcing such an outstanding set again.

“Such a large collection of such uniform and fine quality is almost very difficult to come by, especially considering they’re only minimally oiled” (usually stones of this type are moderately to heavily oiled).

The pendant is eye-catching thanks to its sheer size and exceptional clarity.

Simon’s favorite piece wouldn’t come as a surprise to anybody that knows him well enough, as it’s been his profile photo for several years and it is a 2.05 carat Fancy Vivid Pink Emerald Cut diamond mounted in a classic three-stone setting.

Hailing from the Williamson Mine in Tanzania, this diamond possesses the most spectacular color with a very deep saturation. “Emerald cuts are notorious for their uneven color distribution throughout their table,” Simon shares, “and sourcing one that not only possesses a highly saturated color but also one that is homogeneous throughout the entirety of the stone is extremely rare.”

Accentuated by two white diamond side stones, the pink diamond pops even more!

Think about summer and you’re likely to conjure up vivid images of bright blue oceans, warm yellow sunlight, intensely pink flowers, and so much more.

Opals can be classified into 2 broad categories: precious (also referred to as noble opal) and common (also known as potch). Precious Black Opals, such as those from the opal mines of ‘Lightning Ridge, Australia’, are generally considered the most rare and valuable.

What sets precious opals apart from their common counterparts is ‘play-of-color’. To understand what this means, we need to quickly look at the composition of these stones. Opals themselves are comprised of silicon, oxygen, and water. As a result, they do not have any sort of crystal lattice but rather, are made up of minuscule silica spheres. When light enters a precious opal, it moves through the gaps found between silica spheres. As a result, the light bends and splits, displaying a stunning rainbow-like spectrum of colors.

The word ‘opal’ apparently comes from the term ‘upala’, a Sanskrit word for ‘jewel’ as well as from the Greek word ‘opállios’ meaning ‘to see a change in color’. Opals themselves have a rich history. In the late 18th to early 19th centuries, they were often used in engagement rings due to their immense popularity. Even Queen Victoria herself was an opal enthusiast! In the early 20th century, anthropologist Louis Leakey discovered opals in Kenya, with the opals said to date back all the way to 4,000 B.C.

About 95% of the world’s precious opals come from Australia. In fact, the opal is Australia’s national gemstone.

Natural blue spinel stones are ultra rare and that’s because they receive no treatment whatsoever to enhance their color; they’re literally found radiating so intensely. You could say they woke up like that!

They’re one of the very few naturally-blue gemstones found on earth and being free of needing modification and/or treatment really sets them apart from other stones. What also makes them stand out even further is that blue spinel contain no inclusions whatsoever, making them even more valuable.

Whilst blue spinel comprises of magnesium aluminate, the blue hues come from the stone’s inclusion of cobalt and iron, which work together to project that incredible color. Cobalt is naturally silver but when light reflects upon it, it reveals shades of blue. When large amounts of iron are featured, it intensifies the color to a dark blue. The type of blue you see in a spinel, whether it’s sky blue, or ocean blue, will depend on its levels of iron and cobalt.

Blue spinel stones are largely found in Tanzania, Myanmar, Sri Lanka, and Vietnam.

Another rare precious gemstone is the spectacular pink sapphire. They are comprised of magnesium, chromium, iron, titanium, and copper. It’s the chromium especially that helps to define the pink tones, meaning the more chromium there is, the more intense the shade of pink.

You may have heard of the fascinating confusion between pink sapphires and rubies. Both contain aluminium oxide and both come from the corundum family. Sometimes, an expert-level assessment is needed to make a distinction between the two if they are of very similar shades. If there is 0.9% or more chromium in a stone, it is classified as a ruby but if there is less than 0.5%, it’s classified as a pink sapphire.

Pink sapphires have grown in popularity as their hues are considered feminine and romantic. They were once considered ultra rare as they were mainly found in Sri Lanka, Myanmar, and East Africa. However, more have been discovered in deposits located in Madagascar.

We’re ecstatic to have pink sapphires from Madagascar that have received no treatment whatsoever, as part of our collection. If you’re curious to learn more about sapphires, check out our blog post on these stunning precious gemstones.

Amongst some of the most valuable precious gemstones in the world are Paraiba tourmalines (also known as cuprian elbaite), as they’re only really found in Brazil, Mozambique, and Nigeria, in areas with high copper concentrations (the copper being what gives it that magnificent color).

These incredible stones were only discovered in the late 1980s by Heitor Dimas Barbosa, who found them in the state of Paraíba, Brazil, based on his intuition that something rare was waiting to be unearthed. That is some incredible intuition right there!

Brazilian Paraiba tourmalines are so rare that only one is found amongst every 10,000 diamonds mined. What makes them stand out from other tourmalines is the ‘neon’ glow that radiates from these precious gemstones. The copper found within them produces those stunning shades of turquoise and blue-green. Paraiba tourmalines are so rare in fact, that oftentimes a single carat of it can be worth high five figures subject to its color.

In 2003, more blue-green tourmalines were found in Mozambique and Nigeria. They are often discovered to be 5 carats or more. There has been much debate about whether these can be called Paraiba tourmalines, with some arguing that only those found in Brazil are worthy of the title, whilst others are far more flexible and label them as Paraiba tourmalines due to their exquisite color and exceptionally high value.

The Paraiba tourmalines we have here at Dehres are nothing short of spectacular. To learn more about these magnificent precious gemstones, be sure to check out our blog post on them.

A celebration of nature’s most precious gifts

28.06.2022 | Return to Nature | Trending | Blog

In today’s technology-driven age, we often find ourselves plugged in at all times. We’ve become residents of a digital jungle, so to speak. It’s worth taking the time, however, to just detach from the daily digital grind, and remind ourselves of our roots and the one source of inspiration we have turned to since the very beginning: nature.

Nature has played an invaluable role in the growth of Dehres. Dehres’ Founder, Ephraim Zion, began his career in Israel as a diamond cutter, working with some of the most gorgeous diamonds produced by nature. Upon mastering his skills, he travelled the world and established Dehres as a leader in the jewelry industry. Our designs incorporate diamonds formed over millions of years and we are constantly in awe of the stones we come across on our journey. We thought it would be fitting to take a look at some of our pieces that remind us to appreciate the truly majestic beauty of nature. Beyond extravagance, we hope that each piece carries a sense of serenity and invigorates the wearer’s perception of life.

13.04.2022 | Fancy Colored Diamonds | Investment
Fancy color diamonds are formed naturally out of carbon in the fiery depths below the surface of the Earth that have been kept untampered for millions of years. The discoveries of colored diamonds result from accidental changes made to their chemical structure as they form – a natural anomaly that constitutes its beauty.

A stunning fancy intense bluish-green diamond of 2.80+ carats is elegantly set with a double halo of pave pink and white diamonds. The soft rounded corners give the piece a distinctive plump that adds to its charm. The band is perfectly wrapped in white diamonds completing the dazzling spectacle.   ⁠



Cited by the Gemological Institute of America, only one out of 10,000 carats of fashioned diamonds display fancy color. That number comes to a smaller fraction of one in 25,000 carats for diamonds inheriting intense color. Founded by the same institute, a colored diamond grading system was created to accommodate and admire the different depths of color each stone naturally possesses. The differentiation of color intensity is graded using the terms: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Deep, and Fancy Vivid.


Colored diamonds are prized by their bevy of rare colors, from auctions of Christie’s to the oldest houses of master jewelers. Its scarcity as a natural specimen gifted by nature allows it to command heavy price tags, breaking the million-dollar mark for diamonds showcasing an exceptional body of color supported by considerable carat weight. The high demand for colored diamonds has influenced the appreciation of prices from up to 1 to 2% per quarter.




This fancy pink diamond stands at 3+ carats and receives a clarity grade of internally flawless. Supporting its unmatched beauty is excellent polish and aligned symmetry at the highest level possible.

The combination of the two alluring pink diamond hues creates an unmatched beauty. ⁠ With this ring, the spotlight goes to the 4 carat centerpiece that has an effortless brilliance with it certified as internally flawless. ⁠The ensemble comes with matching square-cut earrings that intensify a romantic aura. ⁠

J340756R , J354267E


Blue diamonds can attribute their distinctive blue tone to the presence of Boron in their unique carbon structure. Being among the rarest of diamonds in the world (second only to red diamonds), blue diamonds tend to command premium prices, with those of Fancy Intense, Deep, or Vivid color intensities being, both, the rarest and most valuable. The 1+ carat Fancy Intense Blue marquise depicted above is exceptionally rare and unique due to the compounded value of having 1. a pure blue color (no secondary tone) 2. a high color intensity of 'Fancy Vivid', and 3. its relatively high clarity (VS).



Conveying signs of love is not limited to pink hues. Romance is reimagined through this heart-shaped fancy intense green diamond of 1.80+ carats destined for a style connoisseur with an eye for the unusual.

⁠A radiant-cut fancy intense green diamond of over 2 carats is framed around an open wreath of pear-shaped and marquise diamonds to create a hypnotic allure.



Dehres perceives owning fancy colored diamonds as not only an investment but a lifelong mission to preserve a curated collection of the world’s rarest diamonds to honor its legacy.

While our previous blog post sheds light on the various colors of Sapphires, from the most sought-after blues, pinks to oranges, this feature addresses the specifics that explain why some sapphires are valued more than others. 

An unheated vivid blue sapphire of close to 7 carats is encapsulated around a swirling display of diamonds capturing the essence of a musical fountain frozen in time. ⁠




The price of any given sapphire is determined by, both, the provenance and the quality of the stone. While sapphires are accessible in various areas globally, only a handful of locations produce desirable, fine quality gems with Kashmir, Burma (Myanmar), Ceylon (Sri Lanka), and Madagascar being the most notable.


Kashmir sapphires are typically the most sought after and command step prices. For instance, the Imperial Kashmir ring is centered on a step-cut sapphire weighing 17.16 carats, which was sold at Sotheby’s for US$4,006,000. Both the allure and the price tag may be attributed to:

1.     Their combined beauty of the vivid (royal or cornflower) blue color and velvety appearance

2.     Their rarity (the mines were only active for a short amount of time and therefore supply is dwindling)

3.      Their historical anecdotes and ‘brand name’


Besides Kashmir sapphires, Burma has several important locations that produce sapphires, the most famous being the Mogok Mine, with production dating back several hundred years. Ceylon, on the other hand, is home to one of the oldest sapphires mines in the world, known for producing some of the world’s largest stones in the world.


Identifying the origins of a gemstone is vital when it becomes an investment. Blue sapphires from Kashmir, Myanmar, Sri Lanka, and Madagascar are top investment choices as visually, their color saturation possesses the highest concentration of blue color possible. The beauty of these blue gems is further illustrated in stones that are spared exposure to heat treatment, intensifying its natural allure.





Dehres offers the most sought-after blue sapphires from deposits of Kashmir to Ceylon and Burma. From royal blue to cornflower blue, find a shade that speaks to your heart. ⁠

J308317E, J354160R


Whether you are in the market for sapphire jewelry or a loose stone for investment, it is essential to note the state of the gemstone. The accredited certification will help specify whether the sapphire is unheated or enhanced. 


The enhancement of sapphires through heat treatment processes dates back centuries and is widely accepted commercially. Gemstone in the rough vary in hues and may not be of desirable color. Heat treatments improve the color and clarity of sapphires while remaining competitively priced compared to unheated sapphires.


Natural, unheated sapphires are more desirable as they highlight and retain the gemstone’s beauty at their purest form. While rarity accounts heavily for why unheated, gem-quality sapphires command steep price tags, other factors, including enhanced specimens’ aesthetical differences, are also considered.

what to look for in an engagement ring?

08.02.2022 | Diamonds | Trends

While you and your beloved partner are in talks of marriage, perhaps it is time to also plan shopping for an engagement ring to gear up for the proposal. With the abundant choices on the market, engagement ring shopping can become overwhelming. Here are our top tips to consider, direct from our Managing Director & Head of Sales, Mr. Ronen Zion, before making a purchase. This is a highly-recommended read before exploring further. 

3+ carat pear-shape diamond engagement ring complemented with two smaller 0.30 carat pear-shape side diamonds



These quality gradings are reliable indicators when assessing the value of the diamond:

– Cut: A grading of how well a diamond is cut. The construct of the diamond affects how it reflects light. Also refers to the shape.

– Color: A measurement of how colorless a white diamond is.

– Clarity: A grading of how flawless a diamond is, both internally and externally.

– Carat: A weight measurement that can give you an idea of how large a diamond is. This is sometimes overlooked, as certain cuts appear larger than the other diamonds of their same carat weight. 


“This is definitely one of the most fun parts of the engagement ring purchase journey”, notes Mr. Zion.

If your significant other has given you some indication of their personal preference(s), then your consultation is all smooth sailing. If not, Mr. Zion recommends looking at their personality, hand shape, and engagement ring trends for inspiration. “Opting for a round brilliant stone is always a good, timeless choice. However, we have definitely noticed an increase in oval, pear, radiant, and emerald cut sales when it comes to engagement rings”. 

Remember, round brilliant diamonds command a premium over your other shapes, while fancy shape diamonds, such as pear, marquise, oval etc. also retain their value.

3+ carat emerald-cut diamond with trapezoid side stones; a popular choice for the more modern individual.



At Dehres, you can select between Platinum and 18K gold. Alloying pure gold with other metals could not only increase the hardness and durability of the gold, but also give you what we recognize as rose, white, or yellow gold. If choosing white metal for the band, “we recommend using platinum, as it feels sturdier and is more resistant to, both, tarnish and scratching”.


After determining the center stone’s shape and metal of choice, comes a decisive move on the setting style. “Seeing as this ring will be worn forever, we often suggest the Client opt for a timeless setting that will always be loved”, shares Mr. Zion. You could choose a classic solitaire or add a little more detail with either two complementary side stones, a pavé-set Halo, or channel-set band. However, the options are endless and range from split shank, chevron, East-West, or tension settings, all being good choices [See below for just some of the many ring settings offered at Dehres]


When purchasing an engagement ring, budget is always an important factor. In order to stick to your original budget, Mr. Zion recommends playing around with the carat size, color, and clarity, to find a stone that is most suited to you and your values. While some select a larger carat size, others opt for colorless or less included (more flawless) diamonds. “When it comes to engagement rings I always advise my Clients to go for color over clarity (with the exception of D colored diamonds, which command premiums),” notes our founder, “with most people opting for 1-3 carat diamonds of D to H color and VVS to VS clarity, with some even selecting SI”. Regardless, always keep an open mind as your preferences may shift when seeing things in real life.

A timeless, brilliant round diamond in a solitaire setting



While an engagement ring holds sentimental value by marking an important milestone for a couple, it is also comes at a higher value. All diamonds at Dehres are accredited and certified by the Gemological Institute of America (GIA) which assures your purchase.


Going custom is a viable route if the range of pre-set engagement rings do not match your expectations. Dehres offers bespoke services where our customers gain access to rare, world-class diamonds. The tailored service invites you to work closely with our experienced sales team and award-winning designers, to create your alluring jewel that highlights the beauty of the stone and reflects your essence.

Statement Jewelry to Welcome the Lunar New Year

18.01.2022 | Precious Stones | Trends

The Chinese zodiac wheel will soon rotate, as 2022 is the Year of the Tiger. The Tiger denotes strength, rebellion, impulsiveness, and braveness. In Fengshui context, the characteristics specific to this zodiac sign encourage a year filled with bold actions. 2022 invites a Water Tiger. Water is a powerful natural force to conquer fire and tackle obstacles in its path.

Make a note of injecting greens, reds, and yellows as accents in the form of jewelry to bring prosperity and vitality according to the Chinese scale of color symbolism as you visualize the new year ahead.


Deck out in luscious green emeralds to reap the positive energy embedded in the generative color. Through the lens of Chinese culture, green symbolizes health, patience, sensitivity, harmony, wealth, and purity.

The spotlight of this regal creation is on the pair of impressive pear-shaped Colombian emeralds of close to 40 carats in total which perfectly encapsulates the vibrant energy of the spring season. Resembling the delicate florets of a blooming flower, the pair of emeralds are complemented with oval-cut diamonds and surrounded by pear-shaped diamonds. 

J372739E , J319508EP

A plump oval-shaped Colombian cabochon emerald of 3.17 carats is surrounded by marquise diamonds for a modern framing. Peeking through the frame are 18 karat yellow gold prongs that secure the main stone for a subtle visual contrast. The band is set with a unified row of sparkling round diamonds to complete the look with luxuriousness.



Red is a prominent color in Chinese culture. People wear red during weddings, festivals, and significant celebratory events for its uplifting symbolism of happiness, beauty, vitality, luck, and success.

An artful creation inspired by the red pigments of seasonal leaves. Three round-cut rubies form the basis of the design with intertwined details to replicate the organic lines of nature.


An oval-cut Burmese Pigeon Blood ruby of 10.08 carats is set with an 18 karat double claw prong setting for contrast. The trapeze-cut diamonds on the side paired with a slender band allows your finger to appear long and elegant.



Yellow of a golden hue is held high in prestige. Only ruling figures throughout Chinese history were able to adorn the color, including the emperors of Imperial China. Royal palaces, altars, and temples are decorated in yellow to intensify the symbolism of neutrality and good fortune. Until today, yellow remains heavily celebrated for its prosperous values.

Relatively modest in design, the clean lines make it a versatile piece for daily attire. An emerald-cut fancy vivid yellow diamond of 2.15 carats is set between two square emerald-cut diamonds of identical size to form a trio ensemble. The band is kept intact to follow a minimalistic aesthetic.

A radiant-cut fancy vivid yellow diamond of 3.45 carats is framed with a halo of round fancy yellow diamonds for a dominant yellow effect. The ring sets mixed-cut diamonds around the main stone to extend its extravaganza.

An elevated proposition to the usual plain white diamond tennis bracelet. This version totaling 43.81 carats is made out of radiant- and cushion-cut yellow diamonds paired with emerald-cut white diamonds to create an allure. Your finger is not left behind, as there is a matching ring centered around a radiant-cut fancy yellow diamond of over 6 carats set between two trapeze-cut diamonds that are purposefully angled to achieve a desired three-dimensional effect.

More Than Pink: Why the Argyle Pink Diamond is a class of its own

09.09.2021 | Diamonds | Industry News | Investment

Dubbed as the most anticipated diamond sale in the world with an invitation-only event taking place annually for the last 38 years, the iconic Argyle mine situated in the remote east Kimberley region of Western Australia makes a definite halt with its last tender of pink diamonds closed for bidding on September 1, 2021.

A sporadic source of light-colored pink diamonds from time to time is a familiar feat, but no mine has produced the consistent quantities and quality that Argyle has. This complete fluke of nature that is bestowed upon us is a mark of an era. 

Beyond beauty and allure, provenance is also another facet behind its glory, as this crop of diamonds is 1.6 billion years old and comes at 0.1% of the Argyle mine’s production. It takes decades of research to discover the right environment that possesses diamonds, and it takes years of investigation to ensure diamond mine will be prepared for recovery, so it’s improbable to experience a discovery like this again.

If you still could not comprehend its rarity in the face of Mother Earth, then perhaps mentioning the totality barely fills two champagne flutes can give you a grasp of scale. 

The scarcity in supply correlates to its soaring prices, fetching double-digit appreciations year after year, but what indeed contributes to the gravitas is its unparalleled pink hues from rose to magenta. You can simply throw the rulebook out regarding preconceptions towards fancy colored diamonds, as Argyle pink diamonds are charted using a unique color guide to define the specificity of hues. While the traditional benchmark follows a loose range of color sensations, the rarity of each Argyle pink diamond is justified with clearer increments.

With the Argyle mine closed, Dehres will honor its legacy by showcasing an array of over 20 pieces of Argyle diamonds ranging from fancy intense pink, vivid pink to fancy red at the Jewellery & Gem World Hong Kong from 17 to September 20, 2021.

This is an opportune moment for gem aficionados to admire its ravishing beauty through an intimate setting, including an over 60-pointers radiant cut fancy vivid purplish pink with unrivalled intensity. Whoever is destined to own one of these intricate beauties won’t just be owning a rare diamond but a rare piece of diamond mining history that it gloriously inherits.

Fancy Color Diamonds: The Silver Lining in your investment portfolio

20.03.2020 | Diamonds | Industry News | Investment

The early months of 2020 have presented themselves to be a rather bleak time, even compared with the previously modest predictions.

Full page photo1

The outbreak of coronavirus (COVID-19) has caused major economic disruption. Predictions for the annual global GDP in 2020 is said to drop to 2.4%, a ½ percentage point less than the original expectation given in November.

This combined with the economic turmoil, as well as, political and geopolitical instability from 2019 doesn’t leave people with much to be hopeful about. This broad-based feeling of uncertainty backfires as the global economy experiences an unprecedented collapse in oil prices, the stock market, and other assets, wiping out trillions of dollars of value overnight. 


Looking up in 2020

In such uncertain times of anxiety and volatility, it is only natural for people to turn to hard assets, such as gold. Widely recognized as a safety valve that financial advisors recommend due to its ability to maintain a strong position, even gold prices have currently plummeted.

Other commodities are looking less attractive right now. Currencies are unstable, the Real Estate market is volatile due to high maintence costs and restrictive regulations, and, the current Interest Rate doesn't leave the public with any incentive to put their money in deposits.

And so the question remains. Where could one put one’s money to promote a relaxed feeling of safety, growth, and security. Now, more than ever, we believe the answer lies within the diamond industry. Specifically, we recommend investing in fancy color diamonds because of their mobility and ability to retain and grow value over time.


Why You Should Put Your Money in Fancy Colored Diamonds

The first and, often overlooked, reason is its miniscule size, which makes it easily transportable. Despite its small size, diamonds encapsulate great value that you can literally hold in the palm of your hand. The fact that you can hold so much capital within your personal possession is rather empowering and gives a sense of security that no other hard asset can provide.

Regardless of what happens to the global economy, the value held within your diamond physically cannot just disappear. In fact, it is easily transportable between borders and even generations. Interestingly, unlike stocks and shares they’re not registered, which means that they don’t need to be taxed. It is not without reason that our tagline is ‘Diamonds for Generations’.

Growth of Fancy Colored Diamonds

In order to display the impressive opportunity of growing your capital with fancy colored diamonds, our team has selected a number of attractive stones that we currently have in house and backtracked what the going rate for them was about fifteen years ago. These examples with some phenomenal anecdotes from our business are sure to convince you that diamonds are a viable option for storing and growing your wealth.  

Diamond Forecast 2020

12.12.2019 | Diamonds | Industry News | Investment

As 2020 commences and with it the turn of a brand new decade, we’d like to share our predictions for diamond, precious stone, and high jewelry trends for the upcoming year.

Dehres has held its position as a pioneer within the industry for thirty-five years.  Our expertise in mining, sourcing, manufacturing, purchasing, and selling to, both, private and corporate clients give us a comprehensive and well-rounded understanding of the current situation. Our founder, Ephraim Zion, a significant industry leader, and staff elaborate.

2019 Recap

The year 2019 was characterized by challenges for the diamond and luxury industries due to economic uncertainty, political instability and a precarious geopolitical situation. Economy wise, we have witnessed various fluctuating stock markets, sharp volatility in share prices and financial turmoil that resulted in huge losses for the various equity fund management companies. The worsening trade conflict between the U.S. and China, as well as, protest movements across Hong Kong and other European and Latin American countries reduced consumer confidence.

All these factors weighed heavily in terms of consumer demand and undermined customers’ confidence. This resulted in a slowdown in the luxury market and caused some oversupply and softening of diamond prices in certain categories.


Looking up in 2020

However, looking towards this year 2020 we are optimistic about improvements in inventory levels. Mine supply and manufacturing cuts leave us witnessing various shortages in the higher end sector of the market. This could help lift prices back to a steady equilibrium, which we hope will continue to rise in the second half of the year. Ultimately, we feel that we have reached bottom and are already seeing signs that prices are beginning to strengthen.

Signing phase 1 of the trade deal with China and the US this month is expected to create a positive sentiment in the business world and hence consumer confidence, which is so essential in supporting and sustaining the consumption of luxury products in general and diamonds, in particular.



The Outcome

In early January we’ve found ourselves lacking inventory for certain high quality and large stones. This shortage is extremely promising to us especially seeing how their prices are already increasing in order to match the increasing demand and depleted supply.

Consequently, we believe that Q1 and Q2 of 2020 present themselves to be the perfect time to purchase such higher-end diamonds. Specifically, we recommend investing in larger diamonds with high to medium color and clarity, prior to their expected rise in price.

We also advise purchasing fancy color diamonds. Diamonds, especially those of high quality, are one of those rare luxury goods whose value won’t diminish over time. This is especially true for fancy color diamonds. Their minimal supply, which is continues to dwindle with the closure of Argyle mine, in addition to increasing demand (171% rise since 2005) make them good long term investments.  As an added bonus, their magnificent beauty is unmatched and can be worn and admired by your friends and family.  


Finally, prices of yellow diamonds have been at an all-time low but a number of events have us anticipating a positive shift; namely, the appearance of the 128 carat Fancy Yellow Tiffany diamond worn by Lady Gaga at last year’s Oscar’s, which quickly went viral for being the 3rd most expensive piece of jewelry worn at the event. From our own experience, we’ve also noticed many choosing yellow diamonds for engagement rings.

Diamonds are beautiful symbols of love that are everlasting. They’re romantic gestures that mark monumental moments with those dear to us. And yet, they are also so much more than that. As a portable means of storing wealth with the potential of growing it, too, diamonds will always remain a strong asset by your side. Thus, we are optimistic about where the industry is headed in 2020.

Types of Sapphire

19.11.2019 | Education | Precious Stones

Captivating in their beauty and their significance, sapphires are recognized as holy stones symbolic of power and strength, and well as kindness and wisdom. Appreciated by cultures and religions throughout history and all over the world, it is no wonder that their popularity continues to grow.

When you imagine a beautiful sapphire, the color blue is often the first thing that comes to mind. However, you may not know that they actually come in all colors of the rainbow, except red because that would be classified as a ruby. In the coming blog we’re going to elaborate on the chemical make-up, rarity, and price points of the various sapphires.


Blue sapphires

Blue sapphires are undoubtedly the most popular of all sapphires. When purchasing one, there are three variables to consider: color, country of origin, and treatment. 

The striking blue color that has led to our association of the gemstone with high royalty can be attributed to the presence of titanium. The two most popular are ‘Cornflower’ blue sapphires and ‘Royal’ blue sapphires, which are strong and velvety. 

Kashmir and Burmese sapphires are definitely favored and command prices that reflect their rarity. As you may expect, the most sought after blue sapphires are those that have the golden trifecta: vivid color, Kashmir origin, AND totally untreated.

Untreated stones are faceted as soon as they are taken from the ground, making them as natural as can be. It is important to note, though, that the term ‘natural sapphire’ does not refer to whether or not the stone was treated but rather, if came from the natural earth or a synthetic lab.

Prior to the early 1900’s and De Beer’s ‘A Diamond is Forever’ campaign that promoted diamonds as the go-to for engagement rings, sapphires were the norm. However, due to their striking appearance and remarkable durability, the blue beauties are making quite the comeback. Some attribute this Prince William’s proposing to Kate Middleton with his mother, Princess Diana’s, Ceylon blue sapphire engagement ring. It is no wonder that the historical and symbolic stone represents the union between two in love. 


Pink Sapphires

The popularity of pink sapphires for engagement rings has also been on the rise with females being drawn to its feminine color. In the past people were more attracted to vivid pinks but, nowadays, we see many gravitating towards the lighter shades because of their airy and delicate feel that pairs beautifully with the ever popular rose gold. Deeper and darker tones of pink are definitely harder to come by, which in turn make them more valuable.

Originally, pink sapphires were found in small amounts in Sri Lanka and Myanmar (previously Burma) but in the late 1990s a deposit was found in Madagascar, which has made these stones much more available.

Pink sapphires attain their color through the addition of chromium and small presence of other elements. Interestingly, stones with considerably high concentrations of chromium are actually referred to as rubies. The addition of some titanium will lead to a more purplish pink, while iron will add a blue tint. 

Pink sapphires also undergo heat treatment but often under much lower temperatures and shorter time frames than blue ones. Getting your hands on an untreated pink sapphire is extremely rare and will require a certificate to prove the lack of treatment.


Orange Sapphire

Orange sapphires are bright and joyful stones that exude happiness and vitality within its owners. This grounding and comforting stone owes its warm orange tone to the presence of chromium and iron in its formation. Orange sapphires range from pale to vivid reddish-orange with, occasionally, a brown tone. As with other colored sapphires, their recognition and popularity is growing.


Padparadscha Sapphire

Although uncommonly seen among the general public, padparadschas have become a favorite of gemologists and gem connoisseurs.  

Padparadscha is a Sanskrit word used to describe the color of a tropical lotus flower. The stone is reminiscent of a romantic sunset that possesses a multitude of warm and soothing colors like orange, which makes the stone so special. This orange hue is due to the presence of, both, iron and chromium. 

Padparadschas are one of the rarest gems in the entire world. Most hail from Sri Lanka, although, some have been found to have originated in Madagascar. Untreated Sri Lankan Padparadshas are the most highly regarded. However, if you’re getting a treated padparadsha, one from Madagascar may be your best bet with greatest value.

Due to their rarity, padparadschas command higher price points that may reach several thousand dollars per carat. It is extremely uncommon to find a padparadscha that is over 2 carats (but if you want to see one, just visit us at our Hong Kong showroom). With the engagement ring of Princess Eugine being a Padparadscha encircled by diamonds, forming a delicate flower, the stone has increased in popularity. 


Other Sapphires

Other than the four aforementioned sapphires, you can also find a multitude of other colors and also different types of sapphires, such as the star sapphire. Star sapphires achieve their unique look through ‘asterism’, a truly special phenomenon that displays a six edged star, which floats on the surface of a cabochon sapphire. 

Dehres Collection

We proudly hold a wide collection of precious sapphires including, both, heated and unheated from countries such as Sri Lanka, Madagascar, and Tanzania. We invite you to make an appointment and view our collection of loose and mounted sapphires. 

Ruby 101

11.10.2019 | Education | Precious Stones

For thousands of years, rubies have been recognized as one of the most valuable and captivating precious gemstones. Their bold color, sheer rarity, scintillating brilliance and profound historical significance have transformed rubies into the ultimate expression of power and passion. These extremely desirable stones command increasing per-carat prices with every passing year. However, not all rubies are created equal. In the following blog, we’re going to expand on a number of Ruby treatments and sources that result in varying prices.  

What are rubies made of?

Rubies are a part of the Corundum family, similarly to Sapphires. They are one of the second hardest materials, second only to diamonds and moissanite, making them not only beautiful but also very durable. Pure corundum is colorless and made up of oxygen and alumnimum. In the case of rubies, though, a small presence (around 1%) of chromium replaces aluminum, which makes it appear red. This is because chromium atoms reflect light that is in the red part of the light spectrum.

Rubies can come in a variety of colors from deep blood red to light pink. A pink enough ruby may be considered a pink sapphire. Despite chemically being the same, the percentage of chromium creates difference between them - above 0.9% chromium classifies a stone as Ruby, whereas a chromium presence of less than 0.5% is classified a Pink Sapphire. Please note, some jewelers will sell pink sapphires as light red rubies since rubies tend to command higher prices than sapphires.


Ruby's Historical Significance

Included as part of the five Cardinal Gems, Rubies hold an important role in history and in our hearts. The Sanskrit name for Ruby is ratnaraj, or ‘King of Precious Stones’ and Ancient Hindus believed owning a ruby would bring about peace with their enemies. The origin of the name Ruby comes from the latin word for red; ruber. It is the distinguishing red color that draws our association of rubies with flame-like passion, power, love, and desire. Among the Royal British family, rubies are valued for their ability to protect, hence a 170 carat ruby as the center stone of the royal crown.  

Heated Rubies

More often than not, mined Rubies have a rather dull appearance. In order to enhance their color and luster, Rubies are often treated with heat. If you are on the market shopping for a Ruby adorned piece of jewelry, it is safe to assume that it is heated since only 1-2% of the world’s Rubies reach the market untreated. Rubies that come with certification that proves no evidence of any heat treatment command premium prices over their heated counterparts.

These heated rubies are exposed to high temperatures that dispel impurities and enhance the gemstone’s color and luster. This heating removes the purpleish tint, which yields a more pure red color. With regards to impurities, heating gets rids of ‘silk’, which are microscopic inclusions that cause the gem to be more opaque. On the other hand, heating can also cause ‘recrystallization’ of the silk, which makes them more prominent, therefore giving the stone a stronger asterism.

The process of heating has been used for hundreds of years and is considered a common and acceptable industry practice. It is important to note that heated rubies don’t require any special care as the heating treatment is permanent (i.e. doesn’t degrade over time).


Pigeon's Blood

Pigeon blood rubies are the most reputable and valuable of all rubies on the market. The origin of the name ‘pigeon blood’ is a topic of great dispute and no concrete answer. The term was coined in Burma where locals called the finest and most vivid rubies ko-twe ‘pigeon’s blood’ claiming that the perfect ruby is the same color as the blood of a killed pigeon.

Today, “pigeon’s blood” is used to describe the world’s finest and purest reds. The term is extremely sellable and exudes importance and exclusivity. In order to a gemstone to be classified as a ruby, it must be 51% red. However, pigeon blood rubies have a vivid red appearance with a blue (or purple after mixed with red) undertone. This distinct vivid red color is accentuated when set in a gold mounting so that the yellow cancels out this blue undertone.

There are fivemain institutions which grade Rubies, in addition to other recognized gemstones, and these are AGL, SSEF, Gubelin, GIA, and GRS. Each of these use varying measures, including color, presence of silk, fluorescence, etc, to determine whether or not a ruby may officially be dubbed a "pigeon's blood" ruby. In a coming blog post, we will expand on just how each labs grade precious gems. 


Ruby Origins

It is known and recognized, industry-wide, that the finest Rubies come from the Mogok region in Myanmar (formally Burma). According to Richard Hughes, who authored “Ruby & Sapphire: A gemologist’s Guide”, there are two things that distinguish Burmese rubies from their counterparts. The first is the combination of the ‘bluish-reddish body color of the gemstone and the “purer” red fluorescent emission, which together give the gemstone its high intensity color. The second is the presence of the aforementioned silk, which give the color a ‘softness and greater dispersion’ across the face of the gem. This is especially interesting given that

Besides Burma, other notable sources of fine quality rubies include Mozambique, Madagascar, Tanzania, Thailand, and Sri Lanka. According to Hughes and with agreement from the founder of Dehres, Ephraim Zion, this new deposit from Mozambique presents us with rubies with such deep and saturated red colors, that they may be compared with those of Burmese origin. Many of these Mozambique rubies are of such high quality that they attain the title of ‘Pigeon Blood’ while being unheated.

Dehres Collection

We proudly hold a wide collection of precious rubies including, both, heated and unheated from countries including but not limited to Myanmar, Mozambique, Tanzania, and Thailand. We invite you to make an appointment and view our collection of loose and mounted rubies. 

Argyle Mine Closure & The Implications

05.09.2019 | Diamonds | Industry News

Natural colored diamonds are one of nature’s best kept secrets. Among these treasures, the pink diamond has risen and come to the forefront as one of the world’s most intriguing stones generously provided to us by our Mother Earth.

Argyle's Origins

Located in the remote East Kimberly region of Western Australia, the Argyle mine has developed a reputation for producing the most esteemed pink diamonds ever known to man. Its opening in 1983 resulted in a great shift within the diamond market, which brought public awareness to the unmatched beauty of pinks, reds, and violets.  

Arygle’s famed marketing slogan, Beyond Rare, exemplifies the sheer rarity of pink diamonds. To give you some context, these stones account for less than 0.1% of the world’s total production of rough.

Still, Argyle mine is recognized for consistently producing 90% of the world’s pink diamonds with distinctive saturations. In the past, global stock of pink diamonds was sporadic, at best, and the color quality incomparable.

Argyle's Exclusivity

Most people, whether in the trade or otherwise, don’t know much about this revered mine, including where to source the special pinks or just how important they are and this isn’t by coincidence. The Argyle mine has developed a distinct marketing strategy, which emphasizes its exclusivity. 

Argyle hosts an annual ‘by invitation only’ tender as the sole means of procuring their revered jewels. This tender is now recognized as the world’s most important global diamond sale, which includes about 55-65 of the most extraordinary pink, red, and violet diamonds unearthed from the mine. The highlighted stones stand apart from others in their extreme vibrancy and intensity of color.

Invitations are only extended to carefully selected diamantaires and collectors. We can proudly attest to Dehres being invited from the very first year. From personal experience, we’d like to share how it works. Tenders travel to most global major cities, where they’ll accommodate private appointments during allocated timeslots. The location remains undisclosed until a few days before the predetermined date and time.

The setting is most often a suite in a prestigious hotel surrounded by elegantly dressed and gloved professional sales-people, as well as, security guards. To purchase a stone, invited guests submit a one-time anonymous bid carefully thought out by experienced buyers based on their knowledge of the market and market prices. The highest bidder earns the esteem that comes with owning an Argyle-mined diamond. Ultimately, the entire experience boasts illustrious status.

In addition to the exclusivity of the tenders themselves, the Argyle mine adheres to a marketing strategy also used by a number of luxury retail brands,which involves releasing a limited number of inventory to the public. Not only does this drive up brand image, but also demand and, therefore, price. To back this up is an interesting statistic: Since it first opened in 35 years, Argyle has only released 2,500 stones, each of which is inscribed and certified. This is definitely reflected in prices of argyle vivid pinks, which are a 50-70% premium compared with others.

"If you want to have an idea of the price you can look at the reserves of auctions every year; the best diamonds are sold in Geneva so typically of this quality from Argyle they would attract several million dollars per carat," says chief executive Arnaud Soirat.

Argyle Closure

After nearly 4 decades, Argyle mine is expected to close operations, according to mine owner Rio Tinto. Over the last few years, prices for these famed pinks have been rising at impressive rates. However, the mine's closure leads an expected exponential rise due to the limited quantity. Gemologists note that the chances of locating a mine that will produce stones of the same stature and quality are extremely low. Still, even if another source is discovered, it will take another 15 years before the precious diamonds would make it to the market.

For these reasons, we believe that there is no better time to purchase an Argyle pink diamond. It would be a fine investment "yielding long-term returns in excess of 10 per cent per annum" according to executive director at diamond investment firm Australian Diamond Portfolio, Anna Cisecki. 

Argyle & Dehres

Over the years, Dehres has acquired a large sum of the famous Argyle pinks and reds. We are proud of our collection and will be displaying them in, both, the upcoming Hong Kong AWE Gemstone Fair (Booth 9JG-19) and the CEC Jewellery Fair (Booth GH-C04). 

However, here are some stones we'd like to highlight beforehand. The first is a Pear Shaped Fancy Intense Purplish-Pink VS2 stone weighing 0.65 carats. Did you know that only one in one hundred thousand diamonds possesses a color deep enough to quality as 'fancy'? Next is an Oval shaped Fancy Visit Purplish-Pink SI1 diamond at 0.66 carats. Finally, we have an impressive 0.67 carat Fancy Red VVS1 Radiant cut diamond. 

paraiba tourmaline

12.08.2019 | Gemmo-knowledge

Paraiba Tourmalines are among the rarest and sought after gemstones in the world right now. Since their recent discovery in 1988, they’ve also become one of the most valuable. In this first edition of the House of Dehres Blog, we will be answering all your questions about this newly revered precious gemstone.

The Biggest Paraiba Ever Seen…

History of Paraiba Tourmalines:

In 1981 Hector Dimas Barbosa, together with a crew of miners, began digging the hills of the Brazilian state of Paraiba. His reason for choosing this specific location was based on nothing but his own intuition, which told him that he would find something remarkable and  ‘truly different’ there. Almost a decade later, in 1988 the first handful of tourmalines were found in the most animated and striking shades of blue, blue-green, and green.

From that very day until now, it is the electrifying neon blue and mint green that have brought paraiba tourmalines to the forefront of the high-end jewelry industry.

Country of Origin

As the name indicates, Paraiba tourmalines were named after their state of origin and place of discovery. However, since then new sources of the mesmerizing stone were found in the African countries of Mozambique and Nigeria. The debate on whether they are ‘equal’ with regards to how special they are varies.

According to the GIA, it is difficult to distinguish between them by standard Gemological testing. However, some more intensive chemical testing will clearly show a difference in the ratios of elements present, namely, copper and manganese. There is an apparent difference in the shade of blue, but then again, many jewelers argue that color is solely a matter of preference rather than that of quality.

Because of this, it is widely agreed across industry circles that tourmalines which look like and contain the same properties as those found in the original mines of Brazil may also be referred to as paraibas (notice the lower-case ‘p’).

Conversely, there are many gemological connoisseurs who believe that the paraibas that hail from Brazil are on a whole other level to those mined in Africa. These devotees claim that equating the two is like saying that African Rubies are just as special as Burmese Rubies.


Of all precious and semi-precious stones, Tourmalines have one the widest array of colors ranging from pink, reds, and oranges all the way to violets, blues, and greens. And yet, before its discovery in the late 80’s, there was never a tourmaline so unique and highly regarded as the beautiful Brazilian Paraiba. 

The Paraiba tourmaline owes its splendid color to copper, an element never before found in any previously discovered tourmalines. Its combination with manganese give rise to the neon greenish blue, blue-green and swimming-pool blue that Paraiba lovers are so drawn to.

Looking at the chemical difference of paraibas from varying locations, we’ve found that paraibas from Brazil contain more copper which lend to purer shades of blue and turquoise, whereas, those from Mozambique contain less copper. The lesser amount of copper yields stones that are generally lighter and less electrifying.

It is important to note that the extraordinary vividness that distinguishes Paraiba tourmalines from other precious stones is unseen until the stone has been properly cut by experienced craftsmen. After being faceted, the gemstones present their intense glow and unique spirit for which they are admired.


Amazing Color Range of Top Quality Paraiba


Tourmaline containing mines in Paraiba, Brazil were discovered 10 years before those in Africa, leaving Brazilian mines almost depleted and supply significantly low.

Paraiba tourmalines are usually small. Larger raw stones are difficult to come by and if found, often contained many cracks and inclusions throughout. It is for this reason that it is extremely difficult to source fine Brazillian paraibas in bigger sizes.

As with other industries, exponential decline coupled with increased demand yields sky-high prices resulting in paraibas developing a reputation as one of the most valuable gemstones on the market today.

To give you some context, fine quality and color tourmaline weighing 2 carats from Mozambique comes at a price of approximately US$10,000 – 15,000 per carat. Meanwhile, a tourmaline with the same specs from Brazil commands a per-carat price of US$40,000 – 80,000. For your reference a 2-carat white diamond (D color Flawless) would cost US$35,000 – 40,000 per carat.

In a Christie’s auction in Hong Kong last May, an exceptional pair of Paraiba-adorned earrings sold for US$2.78million (or US$194,730 per carat). Each Paraiba weighed 7.46 carats and 6.81 carats, respectively.

Ephraim Zion, founder of The House and true Paraiba Tourmaline enthusiast, “you can expect the demand for the precious stone to increase and their prices to match accordingly”.


Our Collection

Some of our favorite loose stones worth mentioning include: a 13 carat Greenish Blue Paraiba Tourmaline from the original Brazilian mines (342949). Another one is a 20 carat triangular-shaped greenish-blue stone (333562).

When integrating Paraiba Tourmalines into our jewelry design, we favor combining its radiant turquoise with white and pink diamonds, both of which accentuate its vividness of color. Paraibas make for beautiful center-stones in rings, necklace pendants, and dangling earrings.


10.7.2019 | DIAMOND TRENDS

Jewelry trends for this season have put great emphasis on earrings. On the runways, we’ve seen statement earrings so long and exaggerated that they simply can’t be missed. From experience, we know that diamonds don’t need to be over the top to catch all of the attention. Whether your personal take on accessorizing is more minimalistic or extravagant, the House of Dehres is sure to provide you with earrings that will elevate your style and confidence.


The earliest records of hoop earrings have dated back to the Sumerians in 2500B.C.E. Over history, various civilizations adorned their women’s (and men’s) ears with, often, golden hoops. In the last century, hoops were popularized by Cher and Madonna and are now, quite literally, back and bigger than ever.

Fusing the history heavy and very trendy hoops with classic diamonds is sure to turn heads. However, these are far from your standard round ones. Our award-winning designers have, once again, reinvented the classic hoop and transformed them into edgy time-pieces which are guaranteed to bring an element of chic, whether worn with your daily office-wear or an elegant gown.


Asymmetric earrings are a great way to decorate your ears in your own personal style. Asymmetric means different things to different wearers. To one it might be choosing to wear one earring of two different pairs that you own. An example of this would be choosing an over-the-top dangling earring for one ear and a simple stud to balance it out on the other. However, to another wearer, asymmetric might mean purchasing earrings that were created to showcase their mismatched beauty, such as in the case of our white and yellow diamond earrings displayed. 



Larger (& Longer) Than Life

Exaggeration appears to be the go-to this season, which is very reminiscent of the 80’s. Whether geometric or floral, dainty or robust, these XXL earrings can make any otherwise understated outfit pop. Featured together are three takes on big earrings by the House of Dehres designers. The first two are all glitter and glam, making any woman feel even more woman when she puts them on. The last pair boasts length perfectly combined with tasteful minimalism. 




Studs for Days

Some trends never go out of style and diamond studs are one of those things. Studs are the perfect minimalistic addition to any outfit. Whether you're wearing a lavish outfit that you would like to balance out or a tailored suit, studs always add a sophisticated sparkle. 

Studs represent sheer minimalism, but in no way do that equate boring. When purchasing your ideal pair, there are a number of things for you to consider, namely the size of the stud, the color of the diamonds, and their cut. White diamonds set in platinum gold are the classic choice but make it your own by trading your traditional brilliant cut white diamonds for a more edgy radiant cut yellow diamond pair.
