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.
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

303.10-carat Golden Canary diamond
303.10-carat Golden Canary diamond

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

73.11 carat yellow diamond

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

FCRF yellow diamonds

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.”

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.

POZ Minerals to Bid for Ellendale Mine

POZ Blina yellow diamonds

Only a year ago, very few in the diamond industry would have heard of POZ Minerals. But the company, better known as a phosphates producer, is trying to build a portfolio of projects in Western Australia that could make it a niche supplier of fancy-yellow diamonds.

POZ announced Tuesday that it was bidding for the Ellendale mine after the state government’s call for investors in the asset last week. While POZ already owns the adjacent Blina mine, it hopes to combine the two assets and solidify its position in the fancy-yellow category, Jim Richards, POZ chairman, explained in an interview with Rapaport News Monday.

Owning both “would result in economies of scale and efficiencies in exploration and development and would be a major step towards building a branded diamond-mining company producing the fancy yellows for which Blina and Ellendale are justifiably famous,” the company added in a statement it released Tuesday.

Richards believes the company is a front-runner in the Ellendale bid, given that it already has four mining leases at Blina and since POZ is the only miner in the area with such a license. It also already has a deal with Bunuba Group, the native titleholder for both the Blina and Ellendale land.

Ellendale comes with some history, however, after former owner Kimberley Diamonds ran up bills and a list of creditors that forced it to close the mine in 2015. That, despite a lucrative supply agreement with luxury jewelry Tiffany & Co. for its fancy-yellow diamonds.

Richards is hoping to reestablish that partnership and forge new ones with other retailers. Ellendale’s yellows have a consistency few other mines can achieve, he explains. Meanwhile, POZ is in talks with retailers in Australia and abroad for similar offtake agreements and branding of yellow diamonds from the Blina mine.

POZ is still in a testing phase at Blina and is looking for investors, or to partner with “an experienced mining company,” before production can proceed. Testing shows that fancy yellows account for about 7% of Blina’s production, while white stones make up 18%, 46% are off-white diamonds, and 29% brown. Of those, 93% are gem content or near-gem content, Richards noted.

A parcel of stones from the mine was valued at an average price of $389 per carat, with the fancy-yellow diamonds estimated at approximately $3,391 per carat.
