RAPAPORT… Luxury jeweler Graff is preparing to cut and polish the exceptional 13.33-carat Lesotho Pink that sold for $8.8 million in February.
The company revealed this week that it bought the stone from Gem Diamonds at a tender in Antwerp. At $656,933 per carat, the sale was the highest average price for any rough diamond recovered at the Letšeng mine in Lesotho, Gem Diamonds said last week without saying who the buyer was.
The purchase comes amid a depletion of the world’s pink-diamond resources, as the mines that produce them become extinct, Graff explained.
“This is the most vivid pink rough diamond I have ever seen,
and it is an exceptionally rare treasure,” said Graff founder Laurence Graff. “I am sure the polished diamond that comes from this rough will be an auspicious addition to our roll call of famous gems.”
