Oppenheimer Blue becomes most expensive diamond sold at auction


A new world record for the most expensive diamond ever to be sold at auction was set yesterday (May18) when the Oppenheimer Blue stone sold at a Christie’s sale in Geneva for $57,541,779 (£39.3m).

This news follows months of striking stones being sold at auction for exceptional prices, however the Oppenheimer Blue is the first diamond to surpass the Blue Moon of Josephine, which sold for £32m at Sotheby’s, Geneva in Nov 2015.

At 14.62 carats, the rectangular-cut Oppenheimer Blue is the largest and best quality blue diamond of its size to ever appear at auction, with a classification of vivid blue. Formerly owned by the world’s most powerful diamond magnate Sir Philip Oppenheimer, it had been estimated to sell for $38-$45m.
