Letseng Diamond Mine Produces 478 Ct Whopper

Gem Diamonds and the Lesotho Government, a 30 percent partner in the mine, announced Sunday the recovery of a 478-carat type II D color diamond which they say has the potential to yield one of the largest flawless D-color round polished diamonds in history.

“Preliminary examination of this remarkable diamond indicates that it will yield a record breaking polished stone of the very best color and clarity,” said Clifford Elphick, CEO and chairman of Gem Diamonds.

The diamond was recovered on Monday September 8, and sent to Antwerp for analysis where it was determined to be a type II, D color diamond – the highest color grading available for a white diamond, Gem Diamonds explained.

Letseng has become the premier diamond mine consistently producing high value gem quality stones since it was reopened in 2004 and acquired by Gem Diamonds in 2006. The mine has produced four of the world’s 20 largest rough diamonds, including the 603-carat Lesotho Promise, ranked 15th in size, which sold to Graff Diamonds and partner SAFDICO for NZ$19 million. The 493-carat Letseng Legacy measured as the 18th largest diamond ever found was also sold to the Graff-SAFDICO partnership for NZ$15.4 million.
