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.
Pink Panther jewel
The Darya-ye Noor diamond is believed to be the largest pink diamond in the world. The stone is estimated to weigh 175 and 195 carats and is a light pink color. Its exact weight is unknown because it has been mounted in its brooch setting for over 130 years. The stone is part of the Iranian Crown Jewels and is displayed at the Central Bank of Iran in Tehran.
