On 14 and 15 May 2012, Sotheby’s Geneva will present over 700 lots in its sale of Magnificent Jewels and Noble Jewels. The two-day sale will be spearheaded by one of the most important historic diamonds ever to come to auction: The Beau Sancy. At the heart of the sale will be The Beau Sancy, a diamond which has been the privileged witness of 400 years of European history. Passed down through the Royal Families of France, England, Prussia, and the House of Orange, the celebrated stone was worn by Marie de Medici in 1610 at her coronation as Queen Consort of Henri IV. The 34.98 carat modified pear double rose cut diamond was almost certainly discovered in the area of Golconda in India, the sole source of diamonds until the discoveries in Brazil in the 1720s.
