Description Firestone Diamonds is always looking for a diamond in the rough. With more than 40 years of diamond mining and exploration experience, the company has operations primarily in Botswana and Lesotho. In 2011 it renewed production at its principal asset, the Liqhobong mine in Lesotho. Firestone began production at the BK11 mine in 2010 and maintained operations at its BK16, Tsaong, Orapa, and Jwaneng mines, all in Botswana. Its projects in Botswana are being explored in partnership with South African diamond giant De Beers and junior diamond exploration company Tawana Resources. Audrey Capital Management, JP Morgan Asset Management, and Garmore Investment each holds about 10% of Firestone Diamonds.
