The 196-carat and the 184-carat rough white diamonds
recovered from the Letšeng mine in Lesotho sold on Nov. 24 for $22.7 million (about
$59,833 per carat).

Manufacturer SAFDICO, whose owners include Laurence Graff, won both stones at a tender held in
Antwerp by mine owner Gem Diamonds and the Lesotho government.

Additionally, a 4.68-carat rough blue diamond sold for
$155,000 per carat, the highest price per carat achieved for a Letšeng rough
diamond to date.

“It is very pleasing that Letšeng’s diamonds continue to
attract strong prices,” said Gem Diamonds CEO Clifford Elphick. “I congratulate
Safdico on their purchase of these two remarkable diamonds of top color and
outstanding clarity which are testament to the enduring value of the diamonds
that Letšeng continues to produce.”
