Fancy Color Diamond Prices: First Drop in Almost Four Years

The Index tracking fancy color diamond prices fell during the last quarter, for the first time in almost four years.

The Fancy Color Diamond Index, which monitors pricing data for of all sizes and intensities of fancy color diamonds, fell by 0.7 per cent during Q2 2024, according to an update published yesterday (30 July) by the Fancy Color Research Foundation (FCRF).

The last recorded fall was back in Q3 2020 – in the depths of the Covid crisis – when the Index also fell by 0.7 per cent. That came after two quarters when sales were too slow for the FCRF to produce figures at all.

The trend over the last year or so has been of slower growth. The Index was up 1.3 per cent in Q1 2023, followed by +0.5 per cent (Q2); +0.4 per cent (Q3); +0.1 per cent (Q4) and +0.1 per cent (Q1 2024).

The New York-based FCRF played down the Q2 dip, describing it as “a minor fluctuation when compared to broader market movements”.

It said in a statement: “This stability is particularly evident relative to the sharper declines in the white diamond market and the Dow Jones index, which fell by 3.6 per cent and 1.7 per cent respectively during the same period.

Yellow diamonds (all sizes, all intensities) suffered the biggest drop, down 1.7 per cent. Pinks and blues were both down 0.3 per cent.

The FCRF said its Index had enjoyed an overall increase of 211 per cent since it began compiling data in 2005. During that time it said the price of yellow diamonds had risen by 56 per cent, pinks by 398 per cent and blues by 248 per cent.

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.

Christie’s Holds 2 Sales Despite Cyberattack

Geneva Christie’s went ahead with two of its Geneva auctions, one for jewelry and one for watches, despite the fact that its website has been down since late last week following a cyberattack.

“The Yellow Rose” diamond, pictured above, was the top lot in its “Magnificent Jewels” sale in Geneva.

The 202 ct. Yellow Rose diamond sold for $6.7 million at Christie’s Magnificent Jewels sale in Geneva on Wednesday.

On Tuesday, a smaller but historically significant yellow diamond the 101.29 ct. fancy vivid Allnatt was pulled from Sotheby’s Magnificent Jewels auction at the last minute, despite carrying a $6.1 million to $7 million estimate.

101-ct Allnatt Yellow Diamond Could Fetch $7.2m

The 101.29-carat Allnatt diamond, described as one of the world’s most significant fancy vivid yellow stones, is to be auctioned at Sotheby’s Geneva, with an estimate of $6.2m to $7.2m.

The Type 1a gem, from South Africa, was named after the British racehorse owner and art collector Major Alfred Ernest Allnatt, who bought in in the 1950s. He had it mounted in a brooch by Cartier.

The Allnatt forms the heart of a flowerhead composed of openwork, brilliant-cut diamond-set petals enhanced with baguette diamonds.

It was last offered at auction in Geneva in May 1996 – as the ‘Property of a Lady’ – and sold for just over $3m. At the time it weighed 102.07 carats and was graded fancy intense yellow by the GIA.

It was subsequently repolished to its current 101.29 carats, which bought the color up to fancy vivid yellow.

The Allnatt diamond leads the Magnificent Jewels and Noble Jewels sale on May 14.

Slower Growth for Fancy Colour Diamond Prices

Fancy colour diamonds saw slower growth in the last three months, with an increase of just 0.5 per cent in the FCRF Index, which tracks prices across all colours, sizes and intensities.

That compares with a 1.3 per cent rise during the first quarter of 2023, as reported by the New York-based Fancy Colour Research Foundation, with the biggest increases among yellows.

During Q2, yellows diamonds again drove the increase, with a rise of 6.5 per cent across all categories. Pinks were up 0.2 per cent and blues rose by 0.6 per cent.

The FCRF noted that fancy colour diamonds had again out-performed white diamonds, which saw prices fall 3.5 per cent during the quarter.

Board member Eden Rachminov said: “The first six months of 2023 were intriguing. We experienced notable spikes in certain sub-categories within the yellow category, particularly in the intense and vivid grades with a high inner-grade.

“Meanwhile, the blue and pink categories remained stable. If the world economy continues to maintain its positive momentum, we can anticipate a robust price behavior after the summer.”

Fancy colour diamond prices up 3.9% in 2022

*Only one in 10,000 diamonds found are coloured, according to the Gemological Institute of America.*

Average prices for fancy coloured diamonds of any size climbed by 3.9% in 2022, led by yellows and pinks, the Fancy Color Research Foundation (FCRF), a non-profit that promotes transparency and fair trade in the market, said on Wednesday.

The industry body said prices for all yellow diamonds climbed by 4.6% from the previous year, followed by a 3.9% rise in pinks and 1.8% in blues.

The improved prices reached by these diamonds, the FCRF said, contrast with the annual decline in white diamonds prices.

“2022 was a very good year for yellow fancy colour diamonds in all sizes and saturations. It seems like yellow diamonds with high visual grades and in certain shapes increased by more than what is reflected in the Index,” FCRF data supplier, Israel Papushado, said in a statement.

“Pink fancy colour diamonds performed with no significant change in comparison to previous years; however, blue diamonds did not perform as expected, probably due to limitations in the Chinese market,” he noted.

The prices reported by the FCRF are based on its own Fancy Colour Diamond Index, which is built on tracked data for yellow, pink, and blue fancy colour diamonds’ performance in major global trading centres such as Hong Kong, New York, Geneva and Tel Aviv.

Nature bestows fancy colours on about one in every 10,000 rough diamonds of gem quality that are mined around the world.

The precious stones that can be blue, pink or green form a special asset class, relying on a consumer preference for exotic and unusual items. This also means they are less affected by other factors driving supply and demand in the main diamond market.

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.

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. Those include a necklace by Andrew Clunn, set with 28 oval-shaped diamonds totaling over 168 carats, which carries a high estimate of $3 million, and an emerald-cut, 23.59-carat, D-color, internally flawless, type IIa diamond ring with an upper valuation of $2.8 million.

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.

Fancy-Color Price Index Beats Expectations

Prices of fancy-color diamonds slipped marginally in the fourth quarter of 2020 as stability in the yellow category helped the sector stave off a heavier slump, according to the Fancy Color Research Foundation (FCRF).

“Although 2020 was challenging in terms of logistics and travel, contrary to market expectations, fancy-color diamond prices proved to be resilient, with minor price decreases across the board,” the FCRF said Monday.

The organization’s Fancy Color Diamond Index for yellows inched down 0.3% year on year in the three months ending December 31, while prices for blues fell 1.3%. Pink fancy-color diamonds decreased 0.9%, with the overall index slipping 0.8%.

The 1.50- and 5-carat categories were the strongest for fancy blues, increasing 0.5% versus the previous quarter, while fancy-vivid blues decreased 0.6%, led by soft prices for 1-carat stones in that category. Pinks stayed mainly flat compared to the third quarter, with 2-carat fancy pinks seeing the highest rise, up 1.4%. In yellows, the fancy-intense, 5-carat segment grew 0.8%, and the price for fancy-vivid, 3-carat stones was up 0.7%. Fancy-yellow, 1.50-carat diamonds increased 0.6% during the period.

The FCRF believes prices of yellows will continue to remain strong throughout 2021.

“2020 was a fascinating year; wholesalers and retailers alike had to overcome many logistical hurdles in order to finalize simple transactions, while demand for fancy-color diamonds was solid,” said FCRF advisory board member Eden Rachminov. “I expect 2021 to be a bullish year for yellows; their current price is relatively low and I think that a price increase is inevitable.”

The index tracks prices of yellow, pink and blue fancy-color diamonds in Hong Kong, New York, Geneva and Tel Aviv.

Study yields new insight in hunt for rare, valuable yellow diamonds

Yellow diamonds, some with colourless cores

A new study by University of Alberta scientists could help guide the search for rare, high-value yellow diamonds in the Canadian North.

The researchers, led by PhD student Mei Yan Lai, examined the chemical makeup of stones recovered from the Chidliak and Ekati mines in Northern Canada to get a better understanding of how they formed.

“Without this research, we wouldn’t know that two separate formation events occurred, and that the second, more recent event is responsible for the yellow colour,” explained U of A diamond geologist Thomas Stachel.

“The more we know about the origin of these potentially high-value diamonds, the better results for diamond exploration and value creation in Northern Canada.”

Lai said they wanted to understand the origin of the yellow colour in the diamonds from the two deposits.

“Canadian yellow diamonds have never been studied spectroscopically in detail. Our results suggest that the cause is the preservation of unstable single nitrogen atoms preserved inside the diamonds,” explained Lai, who conducted this research as part of her master’s studies in the Diamond Exploration Research Training School under the supervision of Stachel.

The research team determined that some yellow diamonds contain colourless cores, meaning that the yellow outer layers crystallized on top of clearer centres. Lai determined that the yellow diamonds crystallized no more than 30,000 years before the kimberlite eruptions that brought them up to Earth’s surface.

“Our analysis shows that the colourless cores in these yellow diamonds are about one billion years older,” Lai said. “In fact, the carbon isotope compositions and nitrogen concentrations of the colourless cores and yellow outer layers are significantly different, suggesting that they formed in at least two distinct events and involved different diamond-forming fluids.”

The researchers said discovering a potential new source of yellow diamonds in the Canadian North is economically significant, as the previous main source of high-quality yellow diamonds, the Ellendale Mine in Western Australia, was recently shut down.

The discovery of colourless cores in some of the yellow diamonds may also be of interest to the jewelry trade, said Lai.

“Occasionally, rough yellow diamonds lose their vibrant yellow colour after being cut and polished—probably because this kind of diamond has a thin layer of yellow overgrowth on top of the geologically older colourless core,” she said.

The project is a collaboration with Dominion Diamond Mines and Peregrine Diamonds Ltd. Part of the analyses were done at the Gemological Institute of America.

The research is supported by a bursary through DERTS, funded by the Natural Sciences and Engineering Research Council of Canada’s Collaborative Research and Training Experience program.

The study, “Yellow Diamonds With Colourless Cores—Evidence for Episodic Diamond Growth Beneath Chidliak and the Ekati Mine, Canada,” was published in Mineralogy and Petrology.
