The Rock

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. It was a privilege to present this legendary stone, first sold by Christie’s in 1918 as part of the Red Cross Appeal. More than a century after that first sale, the diamond was sold after 11 minutes of competitive competition for 14.1 million francs, a world auction record for an intense fancy yellow diamond. We are pleased that a significant portion of the proceeds will benefit the humanitarian efforts of the International Committee of the Red Cross.

The Magnificent Jewels auction also includes 19th and 20th century tiaras, including the Tiara Fürstenberg (estimate 400,000-600,000 Swiss francs), and a pearl and diamond tiara with the brand of the famous Austrian jeweler Gustav Flach. This exemplary handcrafted jewel belonged to her Royal Highness of her Princess of Fürstenberg, born Countess Irma of Schönborn Buchheim (1867-1948), member of one of the most eminent aristocratic families of the Habsburg Empire. A letter in the Fürstenberg archives, directed by jeweler Flach Mediansky & Paltscho, explains the many ways the tiara can be transformed, from a tiara for Viennese high society court dances to a more moderate style with pearls, while the diamond motifs can be worn as a necklace, brooch or hairpins.
