The one referred to as The Rock announces itself as one of the most precious diamonds put up for auction. Christie’s will put it on sale in Geneva on 11 May. Those interested, start saving some money: The Rock is estimated to be between 20 and 30 million dollars. A considerable fluctuation, in any case. It is a 228.31-carat pear-shaped diamond that will be the star at the auction of Magnificent Jewels, as part of Christie’s Luxury Week. It is an exceptionally rare gem mined and polished in South Africa over two decades ago and is the largest white diamond ever to appear at auction.

The Rock will join the very best of legendary gemstones which have passed through Christie’s global salerooms since 1766. The market for diamonds is particularly vibrant and we are confident that this sensational gemstone will capture the attention of collectors across the globe this Spring season.
