Auctioneer shows off 118-carat diamond worth at least $36m
NEW YORK (AP) - A New York auction house is showing off a 118-carat white diamond that's the size of an egg. Sotheby's calls it the greatest white diamond to be offered at auction in terms of size, quality, polish and color.
The oval stone will be auctioned in Hong Kong on Oct 7 and has a pre-sale estimate of US$28 million (S$36 million) to US$35 million. It was discovered in 2011 as a 299-carat rough diamond in an undisclosed southern African nation.
The current record for any white diamond is US$26.7 million. That pear-shaped stone was more than 101 carats. It was sold at Christie's Geneva last spring. The stone being auctioned next month is nearly 20 per cent larger.
