“The stones in the last year or so are selling well above $2 million per carat. That’s not my quote, that’s updates in the market,” company CEO Johan Dippenaar told Reuters.
The 29.6-carat stone was unearthed from the company’s Cullinan mine, about 40 km northeast of Pretoria.
The latest acorn-sized diamond is said to be one of the most exceptional stones discovered during Petra’s operations at Cullinan and may outstrip the price of recent finds. Earlier in 2013, a 25.5-carat blue diamond was sold for $16.9 million.
The largest rough gem diamond ever found was also discovered at the Cullinan mine in 1905 and was presented to the British monarch Edward VII.
