Sotheby’s has reportedly found a buyer for the world’s most valuable diamond, which is said to be worth at least $15 million more than a record-setting blue diamond which sold for $57.5 million recently.  

Two jewellers – Diacore and Mellen – have acquired an ownership interest in the remarkable Pink Star diamond, a report from Forbes said.

Quoting a statement from the auction house, the report said that “the three parties have formally partnered to achieve the value of the 59.60-carat stone, which Sotheby’s holds in its inventory”.

Sotheby’s had previously estimated the value of the Pink Star at $72 million which is the largest internally flawless, fancy vivid pink diamond ever graded by the Gemological Institute of America (GIA).

Sotheby’s sold the diamond for a world record price of $83 million at an auction in Geneva in November 2013 to diamond cutter Isaac Wolf but a few months later revealed that Wolf and his investors had defaulted on the sale. 

The auction house paid the diamond’s seller $60 million, which was the guaranteed price and the diamond remains in Sotheby’s inventory valued at approximately $72 million, the report said

Currently, the world’s most valuable diamond sold at auction is the 14.62-carat Oppenheimer Blue, which sold for $57.5 million at a Christie’s Geneva sale in May this year.
