The 39.34 ct exceptional Type IIb blue diamond which Petra Diamonds recovered at its Cullinan mine on April 1, has been sold to a partnership between diamond miners De Beers and Diacore for more than $40.1-million.

Mined from the Cullinan C-Cut, Petra said on July 13 that it adds to the famous diamonds that have originated from this iconic mine.
The diamond achieved a price of just over $1-million a carat.

CEO Richard Duffy said the sale of the diamond “sets a new milestone for Petra in achieving its highest price for a single diamond and follows the sale of the 299 ct 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”.
