The 15.10 carat De Beers Blue diamond has become one of the most valuable diamonds ever to come to auction after it went on sale at Sotheby’s Hong Kong today.

The stone, which sold for £2million above its estimated price after seven minutes of bidding, is the largest step-cut vivid blue diamond ever graded by the Gemological Institute of America.

Only five blue diamonds over 10 carats have been auctioned before today and this is the first to exceed 15 carats.

The rough stone was discovered by Petral Diamonds in the Cullinan mine in South Africa in April 2021.

Three months later, De Beers and Diacore bought the stone for $40.2 million, renaming it De Beers Cullinan Blue, with Diacore making the polished diamond.

The Cullinan Mine is the source of the largest gem-quality rough diamond ever found – the Cullinan Diamond which was unearthed in 1905.

The two largest cut stones in this historic rough diamond are now part of the Crown Jewels and seven other major diamonds are the private property of the Queen.

The De Beers Blue diamond weighs 15.10 carats and has become one of the most valuable diamonds ever to come to auction after it went on sale at Sotheby's Hong Kong today.

Prior to the sale, the diamond was exhibited in New York, London, Dubai, United Arab Emirates, Shanghai, Beijing, Shenzhen and Taipei.

Ahead of the sale, Frank Everett, senior vice president and head of sales for jewelry at Sotheby’s, said the De Beers Cullinan Blue diamond is remarkable on several levels.

“It’s rare because of the size. It’s over 15 carats. It’s a bright blue. It’s flawless internally. And really one of the rarest aspects of it is the cut,’ he said.

“I think we’re going to see huge interest in this stone when it finally comes up for auction.

“The jewelry market is very strong right now, really for several years, but one of the strongest segments is colored diamonds. And one of the strongest colors is blue.

The Gemological Institute of America (GIA) has graded the diamond Fancy Vivid Blue – the highest possible color grading according to Sotheby’s, assigned to no more than 1% of blue diamonds submitted to the GIA.

‘Blue diamonds of any kind are rare in the market, but this is the rarest of the rare; nothing of a remotely similar caliber has appeared at auction in recent years,’ Patti Wong, president of Sotheby’s Asia, said in the press release, according to CNN.

“Hundreds of millions of years in the making, this extraordinary blue diamond is certainly one of nature’s finest creations. Now dazzling by the hand of one of the world’s most skilled cutters, it is the chef -of ultimate work, as rare and desirable as the greatest works of art.
