The world’s most expensive diamond per carat has sold for about $27 million US dollars to an unnamed buyer, Sotheby’s Diamonds announced on Friday.
The 102.34-carat jewel is larger in diameter than a quarter and is considered the rarest white diamond ever to be sold. It is the world’s only known D-color round brilliant-cut diamond over 100 carats that is technically flawless, according to the Sotheby’s, which put the diamond up for sale in February.
Of the millions of diamonds the Gemological Institute of America examines each year, only a handful, if any, weigh more than 100 carats, said Tom Moses, executive vice president and chief research and laboratory officer.
“These are accidental freaks of nature really,” Mr. Moses said. Miners are less likely to unearth many more diamonds of this size since no new diamond mines are in the pipeline, he said.
“All indications are that we’ll see fewer of these diamonds,” Mr. Moses said.
