The largest D colour flawless type IIa diamond ever to appear at auction comes up at Sotheby’s Hong Kong on October 7. The 118.28 carat stone is the largest oval shaped internally flawless diamond ever graded by the Gemological Institute of America. Only four other white diamonds of this quality of over 100 carats have ever been sold at auction. All were offered in Geneva salesrooms. The fact that this one is being sold in Asia is testament to the importance of Hong Kong as an international jewellery auction centre.
Discovered in 2011 from the deep mines of Southern Africa the 299 carat rough of this stone is one of the largest found in recent years. The resulting stone is estimated at US$28-35 million which is in excess of the current highest price ever paid for any white diamond at auction.
UPDATE: IT MADE $30.6 MILLION US. This is a world record for any white diamond at auction.
