An exceptional blue diamond weighing 39.34 carats has found a new home with De Beers.

The company, in partnership with manufacturer Diacore, has agreed to pay Petra Diamonds US$40.2 million ($1 million per carat) for the stone, making it the mining group’s most expensive diamond sale to date.

The Type IIb diamond was recovered in April[2] from Petra’s Cullinan mine, located in South Africa.

“This sets a new milestone for Petra in achieving its highest price for a single stone,” says Petra’s CEO, Richard Duffy. “[It] follows the sale of the 299-carat Type IIa white diamond in March of this year and the five blue diamonds comprising the Letlapa Tala Collection in November 2020, purchased by the same De Beers-Diacore partnership.”

Cullinan has produced many notable finds in recent years, including:
