An extremely rare gem known as “The Oppenheimer Blue“, sold for $57.5 million at Christie’s Geneva Wednesday night, making it the most expensive diamond ever to be sold at auction. Mounted on a platinum ring and flanked on either side by a trapeze-shaped diamond, the 14.62 carat Fancy Vivid stone is the world’s largest and best quality blue diamond ever to appear at auction. It was named after its former owner, the late Sir Philip Oppenheimer, a diamond dealer whose family owns the influential diamond company De Beers.
The diamond went for the “hammer price” of $51.3 million with the final $57.5 million total including fees. The rectangular-shaped gem managed to beat the 12.03-carat “Blue Moon of Josephine,” which sold for a world record of $48.4 million in November 2015.
