A 424.89-carat stone found at Petra Diamond’s Cullinan mine in South Africa has sold for just under US$15 million.
Dubbed the ‘Legacy of the Cullinan Diamond Mine,’ the D-colour Type II gem was purchased by Belgium-based Stargems Group in partnership with Choron (Belgium).
“This is a significant sale for Petra Diamonds and an endorsement of the quality not only of the Legacy diamond, but also the Cullinan ore body itself, which is known for its exceptional stones,” said Petra CEO Richard Duffy.
