Lucapa Diamond Company announced yesterday the recovery of a 195 carat diamond, discovered in the Lulo Alluvial Mine in Angola. It involves a type IIa diamond, which occurs only very rarely in nature. Special about this type of diamonds is the fact that they have no measurable nitrogen or boron impurities, making them the most chemically pure diamonds with the highest thermal conductivity that exists. Mostly these diamonds are colorless, but they can also be gray, light brown, light yellow or light pink.
