London—Mining company Gem Diamonds, in cooperation with the government of the Kingdom of Lesotho, recovered a 478-carat diamond from a mine in the African kingdom, the company announced recently.

Recovered from the Letseng Mine, the large piece of rough was sent to Antwerp, Belgium, where it was determined that the diamond was a type II D-color diamond with no inclusions visible in its rough form and of outstanding clarity, according to Gem Diamonds.

The diamond ranks as the 20th-largest piece of rough uncovered in history and has the potential to yield one of the largest flawless D-color polished diamonds in history.

It is the third significant recovery from the Letseng Mine in recent years.

The mine, which was owned by De Beers for many years, yielded the 603-carat Lesotho Promise in 2006 and the 493-carat Letseng Legacy in 2007.

Including the 601-carat Lesotho Brown, recovered in 1960, the Letseng Mine has produced four of the world's 20 largest rough diamonds and the three largest diamonds recovered this century.

"Once again, Letseng has proven its ability to produce extraordinary diamonds and continues to place Lesotho at the forefront of diamond-producing countries," Lesotho's Minister of Natural Resources Monyane Moleleki said in a media release. "We will continue to proudly develop this asset and the rare diamonds that it produces to their maximum value for the benefit of the people of Lesotho."

Established in 2005, London Stock Exchange-listed Gem Diamonds is a global diamond company with operations in Angola, Australia, Botswana, the Central African Republic, the Democratic Republic of Congo, Dubai, United Arab Emirates, Lesotho and Indonesia.
