Rare 10-Carat Blue Diamond Could Fetch $20 Million at Sotheby’s Geneva Auction

A remarkable 10-carat blue diamond, dubbed the “Mediterranean Blue Diamond,” is expected to achieve up to $20 million when it goes under the hammer at Sotheby’s in Geneva on 13 May. The diamond, which boasts the highly coveted “fancy vivid blue” colour grade, represents one of the most prized and rare categories in the world of coloured diamonds.

Discovered in 2023 at South Africa’s famed Cullinan mine, the Mediterranean Blue was originally a rough diamond weighing an impressive 31.94 carats. What followed was an extraordinary journey — a full year of study, including precise analysis to maximise both beauty and value, and six months of planning and expert cutting to reveal the gem in its final cushion-shaped form.

Sotheby’s, which is overseeing the auction, describes the diamond as a standout in its class. Jessica Wyndham, head of high jewellery at Sotheby’s Geneva, remarked, “The market for coloured diamonds continues to go from strength to strength.” Indeed, blue diamonds of this size and calibre are vanishingly rare, and collectors around the world are likely to compete fiercely for the chance to own such an exceptional gem.

Fancy vivid blue is the highest grading for coloured diamonds, denoting a saturation and purity of colour that few stones ever achieve. The Mediterranean Blue, with its intense oceanic hue and exceptional clarity, is a testament to nature’s rarity and human craftsmanship.

Over the years, similar diamonds have fetched extraordinary prices. In 2016, the “Oppenheimer Blue,” a 14.62-carat fancy vivid blue diamond, sold for a staggering $68.7 million at Christie’s in Geneva, setting a world record for any fancy vivid blue diamond sold at auction. That same year, another exceptional blue stone — a 24.18-carat intense blue diamond also mined from the Cullinan site — sold for $25 million, reinforcing the global appetite for ultra-rare coloured diamonds.

The Cullinan mine, known for producing some of the world’s most famous diamonds — including parts of the Cullinan I and II, which are part of the British Crown Jewels — has once again proven its status as a source of legendary stones.

With demand for coloured diamonds surging, particularly among high-net-worth collectors and investors seeking portable, tangible assets, the upcoming sale of the Mediterranean Blue Diamond is expected to draw worldwide attention.

Its appearance at auction not only marks a rare opportunity to acquire a gem of unmatched beauty and provenance, but also reflects the continuing strength and allure of the coloured diamond market — where rarity and story combine to create lasting value.

The Golconda Blue: The Largest Fancy Vivid Blue Diamond Ever Seen at Auction

Christie’s is preparing to showcase something truly extraordinary — The Golconda Blue, a 23.24 carat Fancy Vivid Blue diamond, set to headline the Magnificent Jewels auction in Geneva on 14 May. Held at the Four Seasons Hotel des Bergues, this remarkable stone carries an estimate of between $35 million and $50 million.

Mounted in a ring designed by the legendary JAR, The Golconda Blue is not only the largest Fancy Vivid Blue diamond ever offered at auction — it’s also one of the rarest and most historically significant diamonds in existence.

Its journey through history is as dazzling as the stone itself. Originally owned by Yeshwant Rao Holkar, the Maharaja of Indore — a prominent patron of art and fine jewellery in the 1920s and 1930s — the diamond was first set into a bracelet by Chaumet in 1923. A decade later, Mauboussin transformed it into a necklace worn by the Maharani, immortalised in a striking portrait by Bernard Boutet de Monvel.

In 1947, the diamond was acquired by none other than Harry Winston, who later sold it as a brooch to the Maharaja of Baroda. After years of being held privately, The Golconda Blue is now returning to the public eye for the first time in decades.

Rahul Kadakia, Christie’s international head of jewellery, called it “a once-in-a-lifetime opportunity,” noting the auction house’s long history with legendary Golconda diamonds such as the Archduke Joseph, the Princie, and the Wittelsbach.

The term Golconda itself refers to the legendary diamond mines of Eastern India, famous for producing some of the world’s most luminous, transparent, and pure gems. Among them are historic stones like the Koh-i-Noor, the Hope Diamond, and the Darya-i-Nur — and now, The Golconda Blue joins this rarefied list.

This sale is not just about a diamond. It’s about history, heritage, and the timeless allure of one of nature’s most breathtaking creations.

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.”

Bulgari Laguna blue diamond could fetch $28m in auction

A rare 11.16 carats fancy vivid blue diamond could fetch between 22 to 25 million Swiss francs ($24 to $28 million) when it goes under Sotheby’s hammer next week in Geneva.

Named the Bulgari Laguna Blu, the pear-shape cut diamond boasts a rich blue hue that the auction house qualifies as “extraordinary” and “mesmerizing”.

It is the highest grade blue diamond ever graded by the Gemological Institute of America (GIA) and the third-largest pear-shaped fancy vivid blue diamond to ever go for sale on an auction, according to Olivier Wagner, head of jewellery at Sotheby’s Geneva.

De Beers Cullinan Blue Diamond Could Bring $48M at Auction

Sotheby’s will auction a stone described as “the largest vivid blue diamond ever to appear at auction” on April 27 in Hong Kong.

Sotheby’s estimates that it could bring $48 million.

The 15.1 carat step-cut blue was cut from a rough stone discovered in April 2021. It is “the largest internally flawless step cut vivid blue diamond that the Gemological Institute of America (GIA) has ever graded,” according to a press statement.

“This diamond ranks as one of the best De Beers has ever seen,” said Bruce Cleaver, CEO of De Beers Group. “It is extremely rare and unique, and as the Home of Diamonds, De Beers is pleased to join together with Sotheby’s to bring this diamond to the world.”

Only five blue diamonds over 10 carats have ever come to auction, Sotheby’s notes. Until now, none has exceeded 15 carats.

“Blue diamonds of any kind are rare on the market, but this is the rarest of the rare; nothing of remotely similar calibre has appeared at auction in recent years,” says Patti Wong, chairwoman of Sotheby’s Asia. “Hundreds of millions of years in the making, this extraordinary blue diamond is surely one of nature’s finest creations.”

The diamond comes from the Cullinan mine in South Africa.

She has created two original designs that utilize her signature triangle inlay pattern — for a necklace and a ring.

Meanwhile, 30 jewels from an American private collector will also go under the hammer. The entire group is estimated at more than $6 million and includes one of the most significant collections of Bulgari pieces ever to come to market, Sotheby’s explained.

In total, the auction house will offer more than 200 lots, with the sale forecast to fetch as much as $70.1 million — the highest estimate for a New York Magnificent Jewels sale since December 2018, Sotheby’s added.

20-Carat ‘Okavango Blue’ Diamond Goes on Display

The public can now feast their eyes on a big blue diamond thanks to New York’s American Museum of Natural History. The museum opened an exhibition Tuesday showcasing the “Okavango Blue,” a 20.46-carat oval-cut fancy deep blue diamond on loan from Okavango Diamond Company, which is wholly owned by the government of Botswana.

It has been given a VVS1 clarity grade from GIA. The diamond came from Botswana’s Orapa mine and is the largest of its kind found in the country to date. The Okavango Blue was named after Botswana’s Okavango Delta, a UNESCO World Heritage Site of global importance for biological conservation and diversity. It’s the first time the diamond is on view to the public and sits at the center of a larger presentation about diamonds from Botswana, exploring industrial uses for diamonds and how Botswana runs its diamond industry as well as educating about the different characteristics of diamonds like size, shape, color, and quality. Botswana is the second-largest producer of natural diamonds in the world, behind Russia. Previous

Next “Our natural diamond resources are managed responsibly in a manner that puts the people of Botswana first,” said Okavango Diamond Company Managing Director Mmetla Masire. “There is a strong sense of local pride knowing that these diamonds are improving the lives of Batswana, with profits directly reinvested in education, infrastructure, and public health. “We are so pleased to share with the world the larger story of the diamond industry of Botswana. The Okavango Blue is not just an ordinary 3-billion-year-old polished carbon element, but rather a physical embodiment of the passing of time, a fragment of eternity. Our diamonds tell the rich history and unique journey of Botswana’s development.” The exhibition sits in the Melissa and Keith Meister Gallery in the museum’s new Allison and Roberto Mignone Halls of Gems and Minerals, which reopened in June after a major renovation. The Okavango Blue and its corresponding Botswana diamonds exhibition will run for six months, AMNH confirmed.

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).

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.
