The world’s largest blue diamond breaks the record and is sold for $ 57.5 million at auction

Dubai, United Arab Emirates (CNN) – The world’s largest blue diamond ever put up for auction has sold for $ 57.5 million.

This 15.10 carat “The De Beers Cullinan Blue” gemstone was auctioned off by Sosby’s in Hong Kong within eight minutes of intense bidding among four potential buyers.

And the final price exceeded the figure that the house expected to achieve, that is, $ 48 million. The name of the winner who participated in the auction over the phone was not revealed.

This rare diamond was found in the Cullinan mine in South Africa in 2021, and it topped the world rankings based on the criteria by which colored diamonds are judged.

The gemstone has been rated by the GIA as having “a refined and vibrant blue”, the highest color rating given to only 1% of the blue diamonds rated by the organization.

Sosby’s described the diamond as an “extremely rare” gemstone, and five gemstones weighing more than 10 carats were up for auction. She pointed out that none of them weighed more than 15 carats, “making the appearance of this flawless gem a historic event in itself.”

With the last bid of $ 57,471,960, “De Beers Cullinan Blue” failed to break the record for the most expensive blue diamond ever sold at auction, by a small margin, leaving the 14.62-carat Oppenheimer Blue to continue. She retained the title, after her sale in 2016 earned $ 57,541,779, a difference of less than $ 70,000.

“This diamond has actually never fallen more than once in its life, and is simply the largest blue diamond, measured in volume I have ever seen,” Sosby’s Asia President Patti Wong said in a statement.
