At a Hong Kong auction, a 118.28-carat white diamond broke a world record when it fetched more than $30 million.

The egg-shaped stone has been described as the finest of its kind ever to appear at auction. Earlier estimates valued it at $28-$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.
