Petra Finds, Sells Another Big Pink Diamond
Recovered from its mine in Tanzania, the 32.33-carat colored stone went for $15 million, or more than $460,000 per carat.

London--Diamond miner Petra Diamonds Ltd. announced Thursday that it recently recovered and sold another “exceptional” pink diamond from its Williamson Mine in Tanzania.
The stone, a 32.33-carat piece of pink rough, went for $15 million, or $463,965 per carat.
Petra sold it to Golden Yellow Diamonds on behalf of M.A. Anavi Diamond Group, a Ramat Gan-based manufacturer that specializes in large and colored diamonds.
M.A. Anavi is the same company that bought the 23.16-carat pink diamond Petra pulled from Williamson last November.
The manufacturer paid slightly less per carat for that diamond--$433,938, for a total purchase price of $10.1 million--which, at the time, was billed as the most significant recovery yet from Williamson.
Petra retained a stake in both stones. The company said it will receive 10 percent of the proceeds from the sale of the polished 32.33-carat diamond and 20 percent of the proceeds from the sale of the 23.16 carater.
