Here's how much a rare 32 carat pink diamond was sold for by Petra Diamonds

Petra Diamonds Ltd said on Thursday it had recovered and sold an exceptional 32.33 carat pink diamond from the Williamson mine in Tanzania for $15 million (around Rs 99.8 crore).

The company, which owns the historic Finsch and Cullinan mines, said it would retain a 10% interest in the polished proceeds.

The diamond was bought by Golden Yellow Diamonds on behalf of diamond manufacturer M A Anavi Diamond Group, Petra said. 

Petra has interests in six producing operations: five mines in South Africa (Finsch, Cullinan, Koffiefontein and Kimberley Underground), extensive tailings operations in Kimberley (via its interest in the Kimberley Mines) and one mine in Tanzania (Williamson).

Petra Diamonds is a leading independent diamond mining group and a supplier of rough diamonds to the international market.
