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.
Jubilee Diamond
Dorabji Tata acquired it around 1900 and gave it to his wife Meherbai. She used to wear it during her visits to the royal courts and public functions. The Jubilee Diamond was the largest in the world until 1905 when a bigger diamond was exhibited. It was sold only after his death in 1932 and the money went to the formation of the Sir Dorabji Tata Trust.
