large uncut diamond sold by Petra

LONDON (Reuters) – Petra Diamonds sold a 507-carat uncut diamond for $35.3 million on Friday, breaking a record as the highest price ever paid for an uncut diamond.


 Analysts had estimated the value of the stone, one of the 20 biggest high-quality uncut diamonds, at around $25 million.

 "It is fitting that the Cullinan Heritage should achieve a sale price of $35.3 million, the highest sale price on record ever achieved for a uncut diamond, as it has the potential to produce one of the world's most important polished gems," Chief Executive Johan Dippenaar said.
London-listed Petra said in a statement the gem was purchased in a tender by Chow Tai Fook Jewelry Co Ltd in Hong Kong.
