'Oppenheimer Blue' diamond sells for £35m in auction record
The "Oppenheimer Blue" has fetched 50.6 million Swiss francs (£35 million), setting a new record for a diamond sold at auction.
The 14.62-carat stone, billed as the largest Vivid Blue diamond ever put up for auction, obliterated the Christie's pre-sale estimate range of between 38 million and 45 million Swiss francs (£26-31 million).
The rectangular-cut diamond has been set in a ring and flanked by two smaller trapeze-shaped diamonds.
The diamond got its name from the late Sir Philip Oppenheimer, who long oversaw De Beers mining and had given the stone to his wife.
Wednesday's sale ended a two-day run of big-ticket jewellery auctions in Geneva.
The previous record sale for any diamond was 47.8 million Swiss francs (£33 million) for the 12.03-carat polished "Blue Moon" diamond in Geneva last year.
