Largest Fancy Vivid Blue Diamond in Auction History Estimated at up to $45M

Christie’s will offer the largest fancy vivid-blue diamond ever to be put up for auction, marking the latest in a string of large colored diamonds coming up for sale, says Rapaport.

The 14.62-carat ‘Oppenheimer Blue’ will lead Christie’s Magnificent Jewels auction in Geneva on May 18, with an estimated value of $38 million to $45 million. The precious stone is named after its previous owner Sir Philip Oppenheimer, who was the chairman of the Diamond Trading Company from 1975 until his death in 1995.

The sale could come close to a world record of $48.5 million set by the 12.03-carat Blue Moon in Geneva at a Sotheby’s auction in November.

A study by the Gemological Institute of America found that of 462 blue diamonds, only 1 percent were fancy vivid, Christie’s said.
