The Beau Sancy, billed as one of the most historically important diamonds to go under auction, has sold for an astonishing US$9,699,618, in Sotheby's record-busting two‐day Magnificent Jewels and Noble Jewels Sale.
During the sale, five bidders competed for The Beau Sancy (lot 595), driving the price to $9,699,618, almost five times the pre‐sale estimate of $2‐4 million. Eight minutes later, it was all over: the celebrated royal gem was won over by an anonymous telephone buyer.
Passed down through the Royal Families of France, England, Prussia and the House of Orange, the 34.98 carat modified pear double rose cut diamond, which experts say came from the Golconda region in India, has been the silent, glittering witness of 400 years of European history. Most notably, the stone sat atop the magnificent crown worn by Marie de Medici in 1610 at her coronation as Queen Consort of Henri IV.
Speaking after the sale, David Bennett, Chairman of Sotheby’s Jewellery Department in Europe and the Middle East and Co-Chairman of Sotheby’s Switzerland, said: “The legendary Beau Sancy is a truly magical stone that has entranced generations of royal owners and continues to exert a powerful influence over all who see it. Its supreme historical importance was reflected tonight in the strength of the bidding and the remarkable result realised."
