Huge Diamond Sells For Over $35 Million

Filed under: Jewelry

Last fall we speculated that a huge 507-carat piece of rough diamond might sell for $30 million. The result was even bigger than anticipated. Petra Diamonds announced that the stone sold for $35.3 million which was the highest sale price ever for a rough stone, an impressive $69,557 per carat. Hong Kong-based Chow Tai Fook Jewellery Company Ltd. bought the rock which has been given the preliminary name "Cullinan Heritage," at a tender in South Africa. The stone is the 19th largest piece of rough unearthed in history and is exceptional both in terms of size and color and clarity.

It is believed that the buyers will seek to sell the stone in China. The rough stone could yield a "D-flawless" clear polished stone of 170-180 carats, a stone which could sell at a huge price. The diamond will be doubtlessly be scrutinized by teams of expert cutters and all possible strategies will be mapped and modeled before the first cut is made, a process which generally takes several months.
