Sotheby’s to Auction 72-ct. Diamond

Sotheby’s will auction off a 72-ct., flawless white diamond for an estimated $10 million to $12 million in its April 10 auction in Hong Kong, which would make it the most expensive diamond ever sold at auction in Asia, the auction house said.

The D-color stone from a southern African mine will be the third largest “pear-shaped” stone ever auctioned globally, Sotheby’s said.

The stone is valued for its size, symmetry, and “Type IIA” rating.
