Oppenheimer Blue Diamond

As the largest Vivid Blue diamond to ever appear at auction, the Oppenheimer Blue diamond sold for a dizzying $57.5 million in Geneva on May 18, 2016. The 14.62-carat diamond was named after its previous owner, Sir Philip Oppenheimer, who is also the former chairman of De Beers. The Oppenheimer sold for well above its asking price of $35 – $45 million; given its unusual beauty, it’s not hard to see why.
