Miners in Sierra Leone have unearthed a 476.7-carat diamond, reports the country's National Minerals Agency. Mining company Meya, owned by Namibia's Trustco Resources (51%) and Germinate Sierra Leone Ltd., discovered the stone in the diamond-rich eastern district of Kono. According to their initial estimate, it is the 29th largest diamond ever recovered, but the company said it was too early to attach a value to the stone. Sahr Wonday, director general of Sierra Leone’s National Minerals Agency, said the latest find “provides a remarkable indication of the potential of the mineral resources” in the area. Two other special diamonds of 19.70 carats and 27.93 carats were discovered on the same day in the same area.
Wonday said the company that uncovered the stone, Meya Mining, has won government approval to export it and the diamond is to be sold at international auction. The latest find comes a little over a half year since a 709-carat was unearthed in March. That diamond is the largest discovered in Sierra Leone in almost a half-century, and is between the 10th and 15th largest ever found worldwide, experts said. Now known as the "Peace Diamond", the massive gem will be autioned on December 4 by the Rapaport Group. The 709-carat stone is currently in Antwerp, where it will be on display at the Antwerpsche Diamantkring's (Antwerp Rough Diamond Bourse) 8th edition of the Antwerp Rough Diamond Days, on Wednesday, Nov. 15.
