The 507-carat Cullinan Heritage diamond has been sold for $35.3 million, the highest sale price on record ever achieved for a rough diamond, Petra Diamonds announced Friday. The diamond was sold on tender in South Africa and was purchased by Hong Kong-based Chow Tai Fook Jewellery.
The purchaser, a Diamond Trading Company (DTC) Sightholder, has not yet disclosed its plans for the diamond.
According to Petra, the price of the Cullinan Heritage, recovered in September 2009 from Petra’s Cullinan mine, reflects the incredible rarity of the diamond. At 507.5 carats, it is the nineteenth largest gem quality diamond ever discovered.
