Petra Sells 168 Carat Diamond for $6.28 Million

The four special diamonds (above)  recovered in the same production  run at the Cullinan mine included a 507 carat, 168 carat, 58 carat and a 53 carat diamonds.

A 168 carats white diamond recovered at the Cullinan mine in South Africa was sold Thursday for $6.28 million, or $37,380 per carat, by African mining group Petra Diamonds. The company did not disclose the buyer’s name.

The stone is one of four diamonds recovered at the Cullinan mine. Two other diamonds, a 58.50 carats diamond and a 53.30 carats diamond, were sold in November for a total of$2.8 million. The fourth stone, a 507.55 carat white diamond, has not yet been offered for sale.

Thus far, the three diamonds have sold for just over $9 million, according to Petra CEO Johan Dippenaar.

The Cullinan mine is a source of high-valued diamonds. The 3,106.75 carat Cullinan Diamond, the largest rough diamond ever found, was found at the Cullinan mine in 1905.

In May of this year, a fancy vivid blue diamond of 7.03 carats from Cullinan was sold for $9.4 million.
