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.
Great Chrysanthemum Diamond
The Great Chrysanthemum Diamond was discovered in 1963 at the Kimberley Mines in the Northern Cape province of South Africa. Weighing in at 198 carats, the rough diamond is one of about only 300 diamonds in the entire world which weigh in excess of a hundred carats. Julius Cohen, one-time protégé of Harry Winston and custodian of the Hope Diamond, purchased the rough stone from its original owners, saving it from the fate of being cut in two. It was Cohen who christened the stone the Great Chrysanthemum, after attending the Chrysanthemum Ball in San Antonio, Texas. When Cohen later learned through Ms. Craggett, his assistant, that the word Chrysanthemum meant "gold flower" in Greek, Cohen made it official.
