Beau Sancy, a diamond of supreme historical importance and one of the most rare diamonds ever to come to auction, will led Sotheby’s Geneva sale of Magnificent Jewelsand Noble Jewels on 15 May 2012.
Passed down through the Royal Families of France, England, Prussia and the House of Orange, the celebrated diamond has been the privileged witness of 400 years of European history. Weighing 34.98 carats, the modified pear double rose cut diamond comes to the market with an estimate of $2-4 million.
Acquired by Nicolas de Harlay, Lord of Sancy (1546-1629), in Constantinople in the mid to late 1500’s, the Beau Sancy diamond is most likely to have originated from the mines in south- central India near the city of Golconda, the source of history’s best-known diamonds, including the Hope, the Koh-i-Noor and the Regent.
In 1604, the Beau Sancy was bought for 75 000 livres (25 000 écus) by Henri IV and gifted to his wife, Marie de Medici. The Queen of France had long desired the stone, particularly after learning that de Sancy had sold a larger stone, today known as the “Sancy”, to King James I of England1. Testament to the importance her Majesty placed on the diamond, the Beau Sancy was mounted atop the crown she wore at her coronation in 1610, as shown in a magnificent portrait by Frans II Pourbus, the Younger, now in the Louvre.
The Beau Sancy diamond will be showcased in an international tour before its auction in Geneva on 15 May 2012.
