The World's Most Expensive Blue Diamond, Revealed

If you want to know where to find the world's most expensive blue diamond, look no further as we're about to reveal everything about the incredible, huge gem.

The world's most expensive blue diamond is called the 'Oppenheimer Blue', and set a world auction record in 2016 when it sold for more than US$57.5 million at Christie’s Geneva Magnificent Jewels sale. T

At 14.62 carats the Oppenheimer Blue is the largest Fancy Vivid Blue diamond ever to appear at auction, and on 18 May, at the Four Seasons Hotel des Bergues in Geneva, it set a new world record for any jewel when it sold for CHF 56,837,000, equivalent to around $58 million.

According to Rahul Kadakia, Christie’s International Head of Jewellery, bidding took well over 20 minutes, starting with multiple bidders, and then settling down to two collectors who were bidding competitively in varying increments to get to the final world record price.

The diamond was named in honour of its previous owner, Sir Philip Oppenheimer, the racehorse owner whose family controlled the De Beers Group, and was the latest in a long line of distinguished blue diamonds to have appeared at Christie’s. They include a blue-diamond ring owned by Marie-Antoinette in 1983, The Tereshchenko Diamond in 1984, the Begum Blue in 1995, and the Wittelsbach  Diamond in 2008.

According to Christie's, Sir Philip developed his eye for extraordinary gems after leaving school, sorting and valuing rough diamonds into sales parcels at De Beers, first in London, and then in the cutting centre of Antwerp.

After distinguished military service in the Second World War, he took took over the De Beers sales cartel in London and set up his own racing stable at Newmarket to own and breed thoroughbreds. He is remembered today as an architect of stability in the international diamond industry and for his incomparable collection of diamonds, led by the magnificent Oppenheimer Blue.

At the sale in Geneva, it's reported that the room was filled with more than 300 clients, with watchers cheering each bid the stone received.
