The Art of Contrast: Why Mixing Coloured Diamonds Creates Extraordinary Jewellery

 

For centuries, white diamonds have been regarded as the ultimate symbol of elegance and timeless beauty. Today, however, the world’s leading jewellery designers are embracing a more artistic approach combining white diamonds with rare coloured diamonds to create striking pieces that are as unique as they are valuable.

From delicate pink diamond halos surrounding a brilliant white centre stone to vivid yellow diamonds framed by soft pink accents, the thoughtful use of contrasting colours can transform an already beautiful diamond into an exceptional work of art.

The result is jewellery that is not only visually captivating but often far more distinctive than traditional all-white diamond designs.

Colour Creates Emotion

The human eye is naturally drawn to contrast.

Artists have understood this for centuries, using complementary colours to create depth, balance and visual impact. Jewellery designers apply the same principles when working with diamonds.

A perfectly colourless diamond surrounded by a halo of natural pink diamonds immediately appears brighter and more vibrant. The soft blush tones create warmth around the crisp white centre stone, producing a romantic and luxurious appearance that cannot be achieved with white diamonds alone.

Similarly, a rich yellow diamond surrounded by pink diamonds creates a dramatic contrast. The warmth of the yellow is enhanced by the cool undertones of the pink, allowing each colour to appear richer and more saturated.

Rather than competing with one another, the colours work together to produce greater visual intensity.

The Rise of Coloured Diamond Combinations

While coloured diamonds have always been prized by collectors, improvements in jewellery design and precision manufacturing have encouraged designers to use them in increasingly creative ways.

Some of today’s most sought-after combinations include:

• A colourless diamond framed by a halo of natural pink diamonds.
• Fancy Yellow diamonds surrounded by Argyle pink diamonds.
• Fancy Intense Yellow centre stones with white diamond halos.
• White diamonds accented with blue or champagne diamonds.
• Pink diamonds paired with white pavé settings.
• Three-stone rings featuring contrasting diamond colours.
• Alternating white and coloured diamonds in eternity bands.

Each combination creates its own personality, allowing jewellery to become an expression of individual style rather than simply following tradition.

Pink Diamonds: Small Stones with Extraordinary Impact

Natural pink diamonds occupy a unique position within the diamond world.

Even very small pink diamonds possess remarkable rarity, particularly those originating from Australia’s now-closed Argyle Mine. Their limited availability has made them highly desirable among collectors and designers alike.

A halo of pink diamonds surrounding a larger white diamond allows jewellers to showcase this rarity without requiring a large pink centre stone.

The effect is remarkable.

The pink diamonds add warmth and sophistication while visually enhancing the brilliance of the colourless centre diamond.

Because the halo consists of numerous carefully matched stones, the overall impression is one of richness and refinement.

Yellow Diamonds Come Alive with Contrast

Yellow diamonds are among the most popular naturally coloured diamonds available today.

When used as the centrepiece of a ring, they radiate warmth and vibrancy. However, surrounding a yellow diamond with carefully selected pink diamonds introduces an entirely new dimension.

The soft pink tones gently frame the yellow centre, making its colour appear deeper and more saturated. At the same time, the yellow diamond provides a striking focal point against the delicate pink border.

Many luxury jewellery houses have embraced this combination because it creates an appearance that is simultaneously elegant, modern and unmistakably distinctive.

More Than Beauty, A Celebration of Rarity

Combining different coloured diamonds is not simply a design trend.

It is often a celebration of rarity.

Natural fancy coloured diamonds account for only a very small percentage of all diamonds recovered worldwide. Finding matching stones with similar colour intensity, clarity and size requires exceptional expertise.

Every carefully matched halo represents countless hours of diamond selection.

The more precisely the colours complement one another, the more harmonious and valuable the finished piece becomes.

The Importance of Colour Matching

Creating a successful coloured diamond design involves far more than selecting attractive stones.

Professional jewellers carefully consider:

• Colour hue
• Colour intensity
• Tone
• Saturation
• Diamond size
• Cut precision
• Overall symmetry

Even slight variations between pink diamonds can affect the appearance of a halo.

Likewise, white accent diamonds must be matched for colour and brilliance to ensure they enhance rather than distract from the centre stone.

This meticulous attention to detail is what separates exceptional jewellery from ordinary jewellery.

Precious Metals Complete the Design

The choice of metal plays an equally important role.

Platinum and white gold enhance the brilliance of colourless diamonds and provide a contemporary appearance.

Yellow gold intensifies the warmth of yellow diamonds while offering a classic, timeless aesthetic.

Rose gold has become increasingly popular for pink diamond jewellery, complementing the delicate blush tones and creating a seamless flow of colour throughout the design.

Some of the most sophisticated creations combine multiple precious metals, allowing each section of the ring to highlight a different coloured diamond.

A New Era of Personal Expression

Today’s clients are increasingly seeking jewellery that reflects their individuality.

Mixing coloured diamonds allows designers to create bespoke pieces that cannot be replicated simply by increasing diamond size or carat weight.

Whether choosing a white diamond embraced by a halo of rare pink diamonds or a radiant yellow diamond accented with white and pink stones, these combinations create jewellery that tells a story through colour, contrast and craftsmanship.

Beauty Enhanced by Contrast

The finest jewellery is rarely about excess it is about balance.

The careful pairing of white, pink and yellow diamonds demonstrates how contrast can enhance brilliance, intensify colour and elevate an already beautiful design into something truly extraordinary.

As coloured diamonds continue to capture the imagination of collectors and jewellery lovers around the world, their thoughtful combination with traditional white diamonds is redefining modern luxury.

When selected with care and expertly matched, contrasting diamond colours do more than create visual impact they create timeless pieces whose beauty lies not only in the rarity of the individual diamonds, but in the harmony they achieve together.

Global Diamond Industry Shows Signs of Recovery: What Is Driving the Rebound?

 

After three challenging years marked by geopolitical disruption, shifting trade routes, and weakened consumer confidence, the global diamond industry is beginning to stabilise and recover. While price volatility persists in certain segments, demand is gradually rebuilding, particularly across the world’s primary luxury markets. Industry professionals broadly agree that the recovery remains uneven, but the direction is clear: a slow yet meaningful turnaround is underway.

Senior figures within the international jewellery trade point to improving economic sentiment as a key catalyst behind renewed interest in diamonds. Changing consumer behaviour is also playing a central role. Natural diamonds continue to dominate global engagement ring sales, retaining their status as the benchmark for long-term value and emotional significance. However, competition from lab-grown diamonds is intensifying, and the market share gap is narrowing.

In major Western markets, lab-grown diamonds are gaining traction, particularly among younger buyers who place greater emphasis on size, clarity, and price accessibility than on tradition. This generational shift is reshaping purchasing decisions and influencing how value is assessed at the point of sale.

Pricing dynamics underscore this transformation. Over the past year, prices for smaller natural diamondsespecially those under one carat have experienced notable declines. At the same time, lab-grown diamond prices have fallen even further, driven by rapid technological advancements and expanding production capacity. Together, these opposing movements have redefined the competitive landscape, prompting consumers to compare value propositions more closely than ever before.

While challenges remain, the combination of stabilising demand, evolving consumer preferences, and market-driven price realignment suggests the diamond industry has entered the early stages of recovery, with long-term implications for both natural and lab-grown sectors.

Rare Half-Pink 37.4-Carat Diamond Unearthed in Botswana

A remarkable two-coloured natural diamond has been discovered in Botswana, astonishing experts with its size and formation. The gem half pink and half colourless weighs an impressive 37.41 carats and measures approximately 24.3 x 16 x 14.5 millimetres, according to the Gemological Institute of America (GIA).

The GIA describes the stone as having formed in two distinct geological stages. Sally Eaton-Magaña, Senior Manager of Diamond Identification at the GIA, explained that the pink section likely began as colourless before undergoing plastic deformation possibly caused by a mountain-forming event millions of years ago. This natural deformation altered the crystal lattice, giving rise to the diamond’s vivid pink hue. The colourless section, in contrast, appears to have formed later under more stable conditions.

Pink diamonds are among the rarest gems on Earth, prized for their beauty and scientific intrigue. Unlike coloured diamonds that owe their hue to trace elements or radiation exposure, pink diamonds result from structural distortions within the crystal lattice. This phenomenon must occur under highly specific pressure and temperature conditions too little deformation and the diamond remains colourless; too much and it turns brown.

“It’s a geological balancing act like Goldilocks,” noted Curtin University geologist Luc Doucet, referencing the fine threshold that determines a diamond’s colour outcome.

What makes this new discovery even more extraordinary is its size. While other bi-coloured diamonds have been documented, they are typically no larger than 2 carats. The 37.4-carat specimen from Botswana represents a significant leap in both scale and scientific importance.

The diamond was unearthed at Lucara Diamond Corporation’s Karowe mine, one of the world’s most productive sources of exceptional diamonds. The Karowe mine has previously yielded some of the most celebrated finds in modern history, including the 2,488-carat “Motswedi” diamond, the second-largest rough diamond ever recovered, and the 62-carat “Boitumelo” pink diamond.

This latest discovery further cements Botswana’s position at the forefront of the global diamond industry and provides scientists with another remarkable glimpse into the complex natural processes that create the Earth’s most coveted gemstones.

Rare purple diamond unearthed at Diavik

Vibrant 0.45-carat gem adds final flourish to Diavik’s closing years.
Just when it seemed Diavik had given all it could give, a rare purple diamond has been unearthed at the Northern Canadian mine – a 0.45-carat stone that stands out in a region better known for producing predominantly colorless gems and the occasional yellow stone, adding a splash of unexpected color as the operation approaches the final years of its mine life.

The discovery, quietly announced by Rio Tinto via social media, comes just weeks after the recovery of a 158.2-carat yellow diamond and a 50-million-year-old petrified log – both of which drew attention to the remarkable geological and historical treasures still surfacing from the remote subarctic site.

“We recently had a unique discovery at Diavik – a rare purple diamond weighing in at 0.45 carats,” the company wrote in a social media post on LinkedIn.

“Diavik diamonds are typically white, so this came as a pleasant surprise,” the post continued. “The purple colour likely comes from a trace element such as hydrogen or a twist in the crystal lattice structure of the diamond. The shape of the rough diamond is known as a ‘makeable’ which means it will likely be cut into a single diamond.”

Though small in size, the stone is striking for its rarity, with colored diamonds of any kind making up less than 1% of Diavik’s total production over more than two decades of operation.

Among them, purple diamonds are the rarest, their distinctive hue typically attributed to hydrogen impurities or plastic deformation deep in the Earth’s mantle – a result of the intense pressure and heat that alters the crystal structure during formation.

In gemological terms, purple diamonds are often classified under the broader category of “fancy color” stones, though few attain the deep saturation necessary for that label. More often, their shades fall within the purplish-pink or violet spectrum, with pure purple standing as one of the most elusive colors in the diamond world.

For Diavik, the recovery of such a specimen near the end of its mine life serves as both a scientific curiosity and a symbolic capstone.

Since beginning production in 2003, the mine has yielded over 140 million carats of rough diamonds – predominantly colorless, with a handful of exceptional yellow stones including the 552-carat “egg” discovered in 2018 and the more recent 158.2-carat find earlier this year.

Yet, while the occasional yellow diamond has offered moments of brilliance, the purple discovery stands out for its singularity.

While not the first purple diamond recovered from Diavik – industry veterans have noted smaller specimens dating back more than a decade – this 0.45-carat stone ranks among the most notable, particularly for its size, clarity, and timing near the end of the mine’s operational life.

Purple diamonds are so rare that only a few notable examples have surfaced globally, often fetching premium prices far beyond their white or even pink counterparts. Their appearance in the trade is sporadic, and their origin even more geographically restricted – making a Canadian purple diamond an especially uncommon occurrence.

Diavik’s purple gem is expected to be cut into a single polished stone, though no details have been released about where it might end up – in private hands, a high-profile auction, or perhaps a Canadian institution.

Whatever its path, the find adds a final chapter to Diavik’s legacy – a small but vibrant reminder that even in its twilight, the remote Arctic mine remains full of surprises.

Petra’s entire interest in Williamson headed for Tanzania’s Pink Diamonds

An agreement has been entered into for the outright sale of Williamson Diamonds Limited, Petra Diamonds announced on Wednesday.

The London-listed and South Africa-active Petra is taking steps to sell its entire shareholding in the Tanzanian entity to Pink Diamonds Investments for a headline consideration of up to $16-million.

This follows Petra’s sale in May of just under half of the asset, in which the Tanzanian government has a stake, for $15-million via long-term technical services contractor Taifa Mining.

Since then, Williamson’s coming under consolidated ownership has emerged increasingly as the preferred way forward.

As a Taifa affiliate, Pink Diamonds is viewed by Petra CEO Richard Duffy as possessing the technical and financial capability to conduct operations in a responsible manner for all stakeholders.

As a wholly Tanzanian-owned company with more than three decades of mining-related experience, Taifa’s working relationships extend to mining majors such as De Beers, Barrick and AngloGold Ashanti. It is now entering a phase of exclusive ownership of the asset where about 1 100 people are employed, most of them Tanzanian.

The mine’s reserves and resources as of June 30 were reported as 37.17-million carats. With liquidity challenges continuing, further capital investment will be required.

“We look forward to working closely with the Mining Commission, the Fair Competition Commission, employees, community representatives and other key stakeholders in completing the sale as soon as possible,” Duffy stated in a stock exchange announcement accessed by Mining Weekly.

In South Africa, Petra operates the Cullinan diamond mine in Gauteng and the Finsch diamond mine in the Northern Cape.

“We’re committed to adopting and adhering to the latest internationally recognised standards throughout all aspects of our business,” said Pink Diamonds chairperson Rostam Azizi, whose family are from the area around Mwadui, the other name for the Williamson mine, which is situated 23 km north-east of Shinyanga in northern Tanzania.

Mining Weekly can report that the discovery of the kimberlite pipe by Canadian geologist John Williamson in 1940 led to ongoing operation since then, making it one of the world’s oldest continuous operating diamond mines. Its yield of 19-million-plus diamond carats includes the 54.5 ct Williamson pink diamond presented to British royalty in 1947.

10.20-Carat ‘Eden Rose’ Diamond Could Fetch $12 Million At Christie’s

Christie’s will offer “The Eden Rose,” a 10.20-carat round brilliant fancy intense pink diamond, as the top lot of its New York Magnificent Jewels auction on June 11. Its estimate is $9 million to $12 million. It is the first time this diamond has appeared at auction.

The Gemological Institute of America report supplied by Christie’s states that the diamond is also internally flawless.

Describing it as an “exceptionally rare gemstone,” Christie’s says the gem, named after the symbol for unconditional love, it is the most significant round brilliant internally flawless fancy intense pink diamond to be offered at auction since the “Martian Pink,” which sold at Christie’s Hong Kong in 2012 for $17.4 million, equating to $1.45 million per carat.

The diamond exhibits a pure pink hue, unlike many natural pink diamonds that typically display secondary hues such as purple, orange or gray. “The Eden Rose stands out for its complete absence of any secondary color, rendering it exceptionally rare,” Christie’s said in a statement.

Rahul Kadakia, Christie’s International head of Jewelry, said in a statement that he is “anticipating significant interest from around the world.”

Christie’s says the round brilliant cut is known for its ability to maximize light reflection and is considered the ideal cut for diamonds.

The Eden Rose is mounted on a ring further adorned with eight brilliant-cut diamonds, ranging in weight from 3.11 to 0.73 carats, and two marquise brilliant-cut diamonds of 2.24 and 1.02 carats.

A Colorful Life: Leibish Shares the Many Hues of His 40-Year Diamond Career

Behind his small and grandfatherly stature is a man who’s not afraid to say anything, and usually does. Leibish Polnauer has been in the diamond industry for over 40 years and runs an extremely successful business. But if not for a crazy fluke and a bit of luck, that business wouldn’t exist.

Polnauer — affectionately known in the trade as simply “Leibish” — welcomed Rapaport’s editorial team to his office in Israel’s diamond bourse to talk about how he got his start, the market for colored diamonds, what he thinks of lab-grown, and how the industry has changed over the years. We also got a sneak peek at some of the jewelry pieces his company is currently working on.

The train ride epiphany
Around 1980, after several years as a diamond polisher and the loss of his job at a factory that went out of business, Polnauer went to London to try to sell a parcel of diamonds. He didn’t manage to offload a single stone, but on the train, on the way back from his business meetings, he saw an advertisement in The Guardian for crown jeweler Garrard, featuring a pear-shaped, brown diamond. Using his abundance of “Israeli chutzpah,” he called the number and told them he had diamonds to sell. The managing director invited him to his office on Regent Street, where he told Polnauer he was making a tiara for a wedding and needed 106 pear-shaped diamonds in four weeks.

Despite his cheeky admission to our team that at the time he had never even heard of pear-shaped diamonds, Polnauer took on the challenge, flew to New York, and secured the stones needed for the piece. He brought them back to London, and Garrard, thrilled with the selection, cut him his first check for GBP 106,000, equivalent to about GBP 1 million ($1.3 million) today.

He used that experience to convince Graff to do business with him. At the time, the jewelry house worked with a sultan whose wife gifted every visitor to their palace with a diamond watch, and Graff was desperate for the pink and yellow diamonds needed to create 50 to 70 watches per year. And thus began Polnauer’s career in the colored-diamond business.

Changing with the times
Throughout the years, Polnauer has watched his business grow from diamond sourcing and manufacturing to include in-house designers that create custom pieces for clients whom they usually never meet face-to-face, but who nevertheless aren’t afraid to drop massive sums of money for a beautiful, original Leibish creation.

One of the most important lessons Polnauer has learned during his time in the colored-diamond industry is that people shop first by color, then by price tag. He has broadened his business to include colored gemstones, because if someone wants a blue diamond but can’t afford it, a sapphire or tanzanite can often present a compelling and cheaper alternative.

Most of the firm’s clients are wealthy 30- to 60-year-olds who have a penchant for color, because, as Polnauer notes, “color is excitement.” They purchase multiple pieces to match their clothing. One client in Texas bought 13 rings in a two-year period because she loved color. Meanwhile, another client ordered a ring for his wife, who then decided she needed earrings to match. When those were ready, she wanted a necklace to complete the set. Polnauer was more than happy to comply, and in a four-day time span, he saw his bank account padded with an additional $500,000.

But working in the colored-diamond industry isn’t always easy. Recently, the company was tasked with sourcing dozens of matching yellow diamonds to be used for a watch created by Jacob & Co. That search took the company on a two-year, international hunt before they finally filled the commission.

Other changes over his more than four-decade career have also been difficult. He has sadly watched as the Israeli diamond-manufacturing sector has diminished in importance with India’s growth, and learned the meaning of providing added value to customers.

“People used to just want to buy a stone, but now they want to buy a product,” he says. “You have to have an internet business; you have to manufacture jewelry. You also have to really be on point with your presentation. When business was face-to-face, if you screwed someone, he would just walk away upset. Now, with the internet, he doesn’t walk away. If he doesn’t like what he gets, he sends it back, and he writes a bad report about you on Google, and you have to pay for the return shipment, so presentation is crucial.”

No lab-grown zone
While many in the industry have welcomed the advent of lab-grown as a way to make money from clients who can’t always afford natural stones, Polnauer pulls no punches about his dislike of what he calls “fakes.”

He believes lab-grown to be detrimental to the natural-diamond industry, because the fall of synthetic prices “pulls down the price of real diamonds.”

He’s also not shy about making it known how damaging he thinks De Beers was with its marketing of lab-grown.

“De Beers made a tremendous self-destructive move by introducing a product which is undermining the basic product they sell,” he explains. “They cannibalized their own sales and did a tremendous disservice to the industry.”

However, Polnauer believes when it comes to lab-grown, there is a light at the end of the tunnel.

“Lab-grown is stealing the story from natural diamonds,” he says. “But there is a saying: ‘When the music stops, the dancing stops,’ so hopefully everything will work out for the best.”

Staying optimistic
His brazenness has seen Polnauer ride out many market ups and downs, the latest challenge being the Israel-Hamas war that started when the latter attacked the country on October 7. When asked if it’s affected his business, he says it has. While he notes that those who want to buy his products still will, and those who don’t never would have anyway, he believes the negative sentiment is “poison” for an industry based on “illusion and sentiment.”

Despite it all, he remains hopeful. When it comes to the future of the trade, he thinks “fancy-colored diamonds will flourish, gemstones will flourish and the jewelry market will flourish, because I’m an optimist, and if you put that positivity out there, everything will work out.”
