Chief Executive Johan Dippenaar told Reuters the latest blue diamond discovery could outstrip recent finds.
"By some margin ... this is probably the most significant stone we've ever, in terms of blue stones, recovered," he said.
"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," he said ahead of the company's first-half trading statement.
Petra Diamonds is due to release figures on production and sales for the six months to Dec. 31 on Thursday, but these will not take into account the find which occurred in January.
