One of the World’s Rarest Red Diamonds Goes on Display

The Winston Red, an extraordinary and exceptionally rare diamond, is now on show to the public — making it the only known pure red diamond of its kind currently on display anywhere in the world.

Weighing 2.33 carats, it holds the distinction of being the fifth-largest pure red diamond known to exist. To put that into perspective, fewer than two dozen red diamonds over one carat have ever been recorded, making this a truly exceptional stone.

It’s now on exhibit at the Smithsonian National Museum of Natural History in Washington, D.C., as part of a special showcase of natural coloured diamonds.

A team from the Gemological Institute of America (GIA), working alongside experts from the Smithsonian’s Department of Mineral Sciences and the Paris School of Mines, have conducted an in-depth examination of the gem.

GIA’s president and CEO, Susan Jacques, called the Winston Red “one of the most exquisite gems on Earth,” noting its intense deep-red colour and fascinating history. Red diamonds are incredibly rare, and among the more than one million coloured diamonds studied by GIA, a mere 0.07% were red — and just over half of those qualified for the elite ‘Fancy red’ grade awarded to the Winston Red.

Through advanced research, GIA scientists have identified the diamond’s colour origin and believe it likely came from either Brazil or Venezuela.

Tom Moses, GIA’s executive VP and head of research, shared his personal connection to the stone, having first examined it back in 1987. He recalled its striking deep red hue and historical significance — a diamond once sold by Jacques Cartier in 1938 to the Maharaja of Nawanagar.

The Winston Red is now the star attraction in a new exhibition at the Smithsonian, which features 40 other rare coloured diamonds from the Winston Fancy Color Diamond Collection. The collection was donated by Ronald Winston, son of legendary jeweller Harry Winston.

This exhibition is a rare opportunity to witness one of nature’s most elusive and captivating treasures — a true celebration of colour, history, and craftsmanship.

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.”

The FCRF tracks pricing data for fancy colour diamonds in Hong Kong, New York, Geneva and Tel Aviv.

Fancy Pink Diamond Fetches $3.5m at Christie’s Auction

A 2.17-carat fancy vivid purplish pink diamond fetched $3.5m at auction, well above its high estimate of $2.5m.

It was the most expensive of a “Perfect Palette” of three colored diamonds that raised a total of $8.4m last week at Christie’s New York April Magnificent Jewels.

The pink diamond (pictured) was a cut-cornered square modified brilliant-cut stone, natural color, SI1 clarity, set with round diamonds in a platinum and 18k yellow gold ring.

A fancy vivid blue cut-cornered rectangular modified brilliant-cut diamond of 2.13 carats, natural color, VS1 clarity, set in a platinum ring with round diamonds, sold for $2.67m (high estimate $3m).

And a fancy vivid orange cut-cornered rectangular modified brilliant-cut diamond of 2.34 carats, natural color, VS1 clarity, set in platinum and 18k yellow gold, sold for $2.19m (high estimate $2.5m).

The sale of over 200 lots – including signed pieces by Belperron, Bulgari, Cartier, Graff, Harry Winston, Hemmerle, JAR, Lacloche, Tiffany & Co., and Van Cleef & Arpels – brought in a total of $35m.

Christie’s said there were bids from 40 countries and 94 per cent of lots were sold.

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.

Rio Tinto unveils Argyle’s largest Fancy Purplish Red diamond

Rio Tinto has revealed its 2018 Argyle Pink Diamonds Tender in New York, including the Argyle Muse, the largest purplish red diamond ever offered.

The Argyle Muse, a 2.28-carat oval shaped Fancy Purplish Red gem, is one of 63 diamonds weighing a total of 51.48 carats being tendered at the event.

Argyle in Western Australia is the world’s only consistent source of rare pink, red and violet diamonds.

The 2018 tender is named Magnificent Argyle in honour of the mine’s role in charting the history of the world’s most coveted diamonds.

Rio Tinto copper and diamonds chief executive Arnaud Soirat said New York was the epicentre for rare fancy coloured diamond collectors and a key market for gems from Argyle.

“This is our 34th Argyle Pink Diamonds Tender and the potency of colours in this collection is a testament to the extraordinary Argyle ore body – rare fancy coloured diamonds, created and limited by nature.” Soirat said.

“The combination of strong demand and extremely limited world supply continues to support significant value appreciation for these stunning diamonds.”

The tender includes five Fancy Red diamonds, two Purplish Red diamonds and three Violet diamonds.

It includes six hero diamonds, which Rio Tinto selected for their unique beauty and were named to ensure a permanent record of their contribution to the history of Argyle’s diamonds.
