Petra Sells Cullinan Blue Diamond To De Beers For $40.18 Million

Petra Diamonds Limited said the 39.34-carat exceptional Type IIb blue diamond recovered at the Cullinan diamond mine in April 2021 has been sold to a partnership between De Beers and Diacore for $40,180,180, payable in cash prior to delivery of the stone.   

Mined from the Cullinan C-Cut, this adds to the famous diamonds that have originated from this iconic mine. The diamond achieved a price of $1,021,357 per carat. Richard Duffy, Chief Executive Officer, said: “This sets a new milestone for Petra in achieving its highest price for a single stone and follows the sale of the 299-carat Type IIa white diamond in March this year and the five blue diamonds comprising the Letlapa Tala Collection in November 2020, purchased by the same De Beers Diacore partnership.”
