Petra Diamonds said on Tuesday it had recovered an "exceptional" 232 carat white diamond at its Cullinan mine in South Africa, the source of many of the worlds largest gems.
The diamond miner, which has five producing mines in South Africa and one in Tanzania, said it expected the diamond (which has no measurable nitrogen impurities), to be sold in the second quarter of its current fiscal year ending June 30, 2015.
In June, Petra unearthed a blue diamond weighing in at 122.5 carats. Analysts from broker Sanlam roughly estimated that it would be worth $35m and the discovery resulted in the shares climbing by more than 6pc in the subsequent week.
