Historisch, kleurloos, prachtig, helder en geveild

A picture taken on May 10, 2012 shows a model posing with the Beau Sancy diamond during a Sotheby's auction press preview in Geneva. A centuries-old diamond passed down through generations of European royalty fetched nine million Swiss francs ($9.7 million) at auction in Geneva on May 15, 2012. The 35-carat "Beau Sancy" diamond was worn by Marie de Medici, Queen consort of Henry IV, at her coronation in 1610. An anonymous telephone bidder purchased the jewel, put on the market by the House of Prussia and described by sellers Sotheby's as one of the "most fascinating and romantic" gems ever to come to auction.
