April 23 Petra Diamonds reported a 55 percent jump in third-quarter revenue helped by the sale of a 29.6 carat blue diamond and strong rough diamond prices.
The diamond miner said third-quarter production rose 15 percent to 743,424 carats, driven by a 34 percent jump in production at its Finsch mine in South Africa.
Revenue for the quarter ended March 31 rose to $163.9 million.
Petra has five producing mines in South Africa and one in Tanzania. (Reporting by Karen Rebelo and Roshni Menon in Bangalore; Editing by Rodney Joyce)
