Rare blue diamond sells for USD $44 million at Christie’s

Christie’s has auctioned one of the rarest blue diamonds in the world for a staggering $44 million.

On Tuesday, the stone called the “Bleu Royal” went under the hammer as one of the highlights of the auction house’s Luxury Week sale in Geneva, far outstripping the presale estimate. It is the first time the stone has been sold at auction, having been in private hands for the past half century.

Set into a ring, the 17.61 carat, pear shaped diamond is considered the largest internally flawless vivid blue diamond to have ever come to auction, and had a presale estimate of $35 million. At the sale, it eventually realised $43.8 million, making it the most expensive jewel sold at auction this year.
