Rethink Yellow Diamond Jewels: How Yellow Diamonds Get Their Colour

Yellow diamonds are making a stylish comeback. Whether offering a warm, earthy glow or a vibrant pop of colour, these fancy-coloured stones bring a fresh, contemporary edge to fine jewellery. They can be worn as neutrals, used as centrepieces, or layered for subtle impact—making them as versatile as they are striking.

The colour in yellow diamonds is the result of nitrogen atoms bonding with carbon within the diamond’s crystal lattice. This bond subtly alters the diamond’s atomic structure, changing the way it interacts with light. Specifically, it absorbs the blue part of the visible spectrum, allowing yellow tones to dominate. The Diamond Certification Laboratory of Australia (DCLA) grades yellow diamonds based on their colour intensity, classifying them as light, intense or vivid. The deeper and more saturated the yellow, the rarer and more valuable the diamond. Curiously, the lighter tones are often more affordable than white diamonds, making them an attractive alternative for those seeking something both elegant and unique.

Why Designers Are Embracing Yellow Diamonds

Jewellery designers are increasingly drawn to yellow diamonds for their warmth, individuality, and unexpected elegance. These stones challenge the norm, offering something joyful and radiant while still being refined. As the jewellery world moves beyond the conventional, yellow diamonds are gaining traction as centrepieces with personality.

How to Wear Yellow Diamonds

Once your collection includes the classics such as white diamond hoop earrings, tennis bracelets, stacking rings or a line necklace it’s easy to introduce a splash of colour. Yellow diamonds pair beautifully with white or rose gold and work well layered with other tones. Go bold with vibrant yellow bangles and cocktail rings, or opt for a more understated approach with a mix of pale-yellow and Champagne diamonds, as seen in Sethi’s neutral-toned confetti styles.

Yellow Diamonds: The Emerging Trend in Engagement Rings

More couples are seeking engagement rings that reflect their personal style rather than adhering to tradition. Yellow diamonds especially those in softer or more earthy tones offer a refined, alternative aesthetic that still feels timeless and romantic.

One designer, Root, recalled a client who brought him a family heirloom: a pear-shaped yellow diamond. He combined it with a matching white diamond to form a heart-shaped engagement ring. Initially, clients were hesitant about yellow diamonds, unsure whether they carried the same prestige. That perception is changing rapidly.

Designer Lau echoes this sentiment. “As our view of what defines a high-quality diamond evolves, I find myself drawn to warmer tones and even imperfect shapes, they feel authentic and special,” she explains. Yellow diamonds are increasingly favoured for their character, individuality, and natural charm.

Why Yellow Diamonds Are Here to Stay

There’s an undeniable joy and brightness that yellow diamonds bring. Whether in soft pastel shades or vivid canary tones, they evoke a feeling of sunshine and optimism, something many people are seeking in their jewellery today.

As the desire for unique and meaningful designs continues to grow, yellow diamond engagement rings are well-positioned to become the next generation’s classic. After all, who can resist a jewel that radiates light, joy, and a touch of the unexpected?

Diavik recovers 158.20 carat ‘miracle of nature’ diamond

One of the largest gem-quality yellow diamonds ever discovered in Canada, has been unearthed from Rio Tinto’s Diavik Diamond Mine.

The 158.20-carat rough diamond is one of only five yellow diamonds weighing more than 100 carats ever unearthed at Diavik in its 22-year history, stated a release.

Diavik’s production primarily consists of white gem quality diamonds, with less than one percent of its production yielding rare yellow diamonds.

Diavik Diamond Mines Chief Operating Officer Matt Breen stated: “This two-billion-year old natural Canadian diamond is a miracle of nature and testament to the skill and fortitude of all the men and women who work in Diavik’s challenging sub-Arctic environment.”

Patrick Coppens, sales and marketing GM for Rio Tinto’s diamonds business, stated: “The beauty and purity of Diavik diamonds continues to excite passions amongst all who see them and we look forward to following the onward journey of this very special diamond.”

45 Carat yellow diamond could fetch $3.5m

A 45.07 carat fancy vivid yellow diamond is forecast to sell for $2.8m to $3.5m at Phillips New York on Wednesday (12 June).

It leads the New York Jewels Auction, featuring colored diamonds and gemstones, period jewelry, and signed jewels by Cartier, Bulgari, and Van Cleef & Arpels.

The square emerald-cut VS1-clarity stone has classic step-cut faceting, considered an unusual choice to best show off the color and draw out the illusion of greater saturation.

The Fancy Color Research Foundation (FCRF) gives the diamond a total visual score of 11 out of 12, based on inner grade (3), color dispersion (4) and undertone (4), noting that despite its depth percentage, excellent polish and symmetry grades, its visual presence translates to “a diamond appearing smaller in carat weight”.

The diamond will realize $77,657 per carat if it hits its high estimate. In March a 15.51-carat VS2 fancy vivid yellow diamond sold for $1.14m – $73,253 per carat – at Phillips Hong Kong Jewels Auction, beating its low estimate.

Graff celebrates yellow diamonds

In celebration of Haute Couture Week, Graff is exhibiting a collection of yellow diamonds at its flagship Paris boutique to complement the unveiling of its new high jewellery necklace

Launched yesterday (4 July 2023), visitors to Sunrise: A Celebration of Graff Yellow Diamonds will discover a world of rarity and lustre through a stunning showcase of high jewellery pieces featuring rare yellow diamonds, accompanied by displays detailing Graff’s storied history with these incomparable stones.

The House’s latest high jewellery creation features an extremely rare 30ct fancy intense yellow pear shape diamond, accompanied by a further 138ct of yellow and white diamonds.

Every element of the piece has been created using the stone-led design techniques for which the Graff atelier is renowned and has been crafted to emphasise the elegant silhouette of the centre stone.

Graff design director, Anne-Eva Geffroy explained: “Before we design, we study each diamond carefully to uncover the secrets that lie within its depths.

“Only then do we design, and when we do, we work to accentuate the natural beauty of each stone.

“The fancy intense yellow diamond set into this piece gives a golden sunshine glow.

“Yellow diamonds bring so much joy.

“It is an honour to be inspired by stones that radiate such beauty.

“The yellow diamonds we work with are exceptional in quality, cut, and quantity.

“Very few jewellers have the luxury of such a wide range of colour.”

In vibrant halos of yellow and white diamonds, stones radiate outwards from the central fancy intense yellow diamond to replicate the rays of the sun.

A perfect synthesis of diamond design and hand-craftsmanship, each bespoke setting has been meticulously assembled by master artisans within the House’s London workshop.

CEO of Graff, Francois Graff added: “Celebrating Graff’s legacy of innovation and leadership in presenting the highest quality rare diamonds, this will be the most significant collection of yellow diamonds that have ever been brought together in one place, including a fancy intense yellow stone of incomparable beauty.

The Star of Bombay is an historical yellow stone that was re-cut and polished by Graff using revolutionary expertise and new techniques.

Since then, Graff has introduced many famous and historical yellow diamonds over the years, including the 118.08ct Delaire Sunrise and the 132.55ct honey-hued Golden Empress.

303ct. Polished Yellow to Hit Auction Block at Sotheby’s

Sotheby’s will offer a yellow diamond weighing more than 300 carats at its upcoming New York auction, where it is expected to bring in more than $15 million.

The pear-shaped, 303.10-carat, fancy-deep-brownish-yellow stone is one of the largest polished diamonds in the world. It is also the largest flawless or internally flawless diamond ever graded by the Gemological Institute of America (GIA), Sotheby’s said Monday.

Initially called the Incomparable Diamond, the stone was recut from its original 407-carat shield shape to deepen the color and brighten the hue, and renamed the Golden Canary. As the highlight of the December 7 Magnificent Jewels sale, it will be offered without reserve, with bidding starting at $1, Sotheby’s noted.

The Golden Canary was first discovered in the early 1980s in a pile of rubble by a young girl playing in the backyard of her uncle’s house, Sotheby’s noted. Miners from the nearby Miba diamond deposit had considered the stone to be too bulky to be diamond bearing and had discarded it. The girl gave the 890-carat rough to her uncle, who sold it to local diamond dealers. The diamond has since been displayed in multiple museums.

“The demand and appetite for [extraordinary colored diamonds] continues to grow,” said Quig Bruning, head of jewelry for Sotheby’s Americas. “Steeped in history, the Golden Canary is one of the most exquisite diamonds to ever be discovered, not only for its sheer size and intensity in color, but for its stunning beauty that is sure to captivate collectors around the world.”

Sotheby’s will showcase the diamond on a world tour prior to the auction, with stops in cities including Dubai; Taipei, Taiwan; Geneva; and Hong Kong.

The Largest Diamond Ever Mined in North America up for Auction

*204.36-carat “Dancing Sun” fancy intense yellow diamond*

A 204.36 carat fancy yellow diamond hits the block at the Christie’s Magnificent Jewels auction on June 8 in New York City. The Dancing Sun, with an estimate of $3.5 million to $5.5 million, is the largest polished diamond ever mined in North America.

It was cut from a piece of rough weighing 552.74 carats. Six smaller diamonds were cut from the same rough, ranging from 14.52 to 1.06 carats, and are also included in the sale. All six are set into rings. The rough diamond came from the Diavik Diamond Mine, the second to open following the great Canadian diamond rush of the 1990s.

The previous record for the largest known gem quality rough ever mined in North America was the 187.66 carat Foxfire rough, also mined at Diavik. It was cut into several gems, including a pair of pear shapes weighing 37.87 and 36.80 carats, auctioned at Christie’s New York in December 2018 for $1.5 million.

73ct. Yellow to Shine at Sotheby’s New York Sale

Sotheby’s will offer a fancy-vivid-yellow diamond ring at its New York sale next month, estimating the piece could fetch up to $3 million.

The cut-cornered square step-cut, 73.11-carat, VS2-clarity jewel by Mayfair designer Glenn Spiro, called The Sienna Star, is one of the largest fancy-vivid-yellow diamonds to come to auction, Sotheby’s said Wednesday. The piece is one of the top items at the June 9 Magnificent Jewels sale. The auction will feature jewelry for the “Roaring Twenties 2.0” as people return to the social scene following long lockdowns, Sotheby’s noted.

A private collection of six jewels with a combined estimate of more than $13 million are another headline lot at the New York sale.

A Colombian emerald and diamond garland necklace by Harry Winston, estimated at up to $2.5 million, and a 13.02-carat Burmese ruby ring, mounted by Carvin French, with a $2 million high valuation, are also part of the collection. Proceeds from the sale of those six items will be donated to charity.

Additionally, Sotheby’s will showcase a Bulgari ring with a 25.29-carat Kashmir sapphire flanked by diamonds, which it expects will bring in up to $3 million. Meanwhile, a modified square brilliant-cut, 3.75-carat, fancy-intense-pink, VVS1-clarity diamond ring, accented by triangle-shaped and round diamonds, is estimated to fetch up to $2.5 million.

The auction house will present jewels from the collection of philanthropist Margaret Jonsson Rogers, the daughter of Texas Instruments founder and Dallas mayor J. Erik Jonsson, as well as property from the estate of Mary Ethel Weinmann, the daughter of Count and Countess André de Limur, it added.

Meanwhile, a pair of aluminum Violet earrings by designer JAR garnered $13,750, more than four times their upper estimate.

6.70 ct Zimmi Yellow Diamond could Fetch $700,000

A rare 6.70-carat VS1 natural fancy deep yellow diamond from the famous Zimmi mine, in Sierra Leone, could fetch as much as $705,000 at auction.

Canary yellow diamonds from Zimmi can command double the price of other fancy yellows because of their uniquely high color saturation levels. Yellow Zimmi stones over five carats are extremely rare.

This gem will lead the Tiancheng International Jewellery and Jadeite Autumn Auction 2020 in Hong Kong on 28 November.

Also at the sale is a pair of Zimmi natural fancy deep yellow diamond earrings 3.03 carat and 3.01 carat with an estimate of up to $320,000.

The Zimmi mine is in the heart of the rainforest region of Sierra Leone where the Mano river marks the border with Liberia.

Yellow diamonds occur when a single nitrogen atom replaces a carbon atom, absorbing the violet and blue light.
