NEW YORK (September 4, 2013)—A 118-carat white diamond that's the size of an egg was highlighted Wednesday at a Manhattan media event.
The diamond will be auctioned on Oct. 7 in Hong Kong and has a pre-sale estimate of $28 million to $35 million.
Sotheby's calls it the greatest white diamond to be offered at auction in terms of size, quality, polish and color.
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 $26.7 million for a pear-shaped stone that was more than 101 carats.
It was sold at Sotheby's Geneva last spring.
The stone being auctioned next month is nearly 20 percent larger.
