Rare 195 Carat Type IIa Diamond Discovered At Lulo Alluvial Mine In Angola

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.

This rare 195 carat diamond is the sixth largest and the 44th +100 carat diamond to be recovered from the Lulo Alluvial operations since mining commenced in 2015. The 195 carat Type IIa diamond is the fourth +100 diamond to be recovered at Lulo this year (2024).
