A 118.28-carat white diamond broke a world record today when it fetched more than USD 30 million at a Hong Kong auction.
The sparkling translucent stone was sold to a phone bidder at the Sotheby's auction for Hong Kong dollars 238.68 million (USD 30.6 million) following bidding that lasted for more than six minutes.
The egg-shaped stone has been described as the finest of its kind ever to appear at auction. Earlier estimates valued it at USD 28-USD 35 million.
The stone, dubbed the "Magnificent Oval Diamond", was discovered in a deep mine in an undisclosed southern African country in 2011.
As a rough stone before being cut, it weighed 299 carats.
The stone, described by Sotheby's as "the largest D colour flawless diamond", has been given the highest quality rating awarded by the Gemological Institute of America.
"D colour" diamonds are rare and colourless and fetch premium prices.
The sale beat the record set at a diamond auction last year, when a 101.73-carat diamond was sold for USD 26.7 million.
Hong Kong has become a centre for jewellery auctions thanks to growing wealth in China and other parts of the region.
