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.
Diamond mining in India
The town of Karwan, near the fortress city of Golkonda, now a suburb of Hyderabad, became the world's largest diamond-cutting and diamond-trading center. Golconda was not close to diamond mines, but owed its status as a diamond center to its location on a major trade route from the mines to the south and east. The diamonds became known as Golconda Diamonds, and in Europe, the word Golconda came to mean a place of great wealth.
