A 22 million Rock




It is 21.7 million Swiss francs, which is equivalent to more than 21.9 million dollars or 20.7 million euros the value attributed to The Rock, the largest white diamond ever sold at auction. At the auction of Christie’s Magnificent Jewels in Geneva, however, the stone did not reach the maximum estimate (about 30 million) even if it exceeded the minimum value (19 million). The Rock has a weight of 228.31 carats, a drop cut and is considered a perfect stone. Another highlight of the auction was The Red Cross Diamond, a vivid yellow gem that fetched 14.2 million francs (14.3 million dollars or 13.5 million euros), with a significant portion of the proceeds to benefit of the International Committee of the Red Cross.

Weighing 228.31 carats, The Rock is the largest white diamond ever to appear at auction. The final lot of the auction featured another extraordinary gem of over 200 carats, the sensational The Red Cross Diamond.
