Petra Diamonds
The Cullinan mine continues to produce large stones. The Cullinan Heritage, a white diamond, was discovered in September 2009. This stone was the 19th biggest uncut diamond ever found and was sold in February 2010 to Chow Tai Fook Jewellery for $35.5m, the highest price ever paid for an uncut diamond. The previous record was held by Gem Diamonds' Leseli La Letšeng, which was bought for $18.4m by Graff Diamonds in December 2008.
Philippe II, Duke of Orléans
On 6 June 1717, under the influence of Law and the duc de Saint-Simon, the Regent persuaded the Regency Council to purchase from Thomas Pitt for £135,000 the world's then largest known diamond, a 141 carat (28.2 g) cushion brilliant, for the crown jewels of France. The diamond was known from then on as "Le Régent".
