The mine, which hosts the world’s highest dollar-per-carat alluvial diamonds, began commercial production in January 2015. Only a year later, it delivered the largest ever diamond recovered in Angola — a 404-carat white stone later named the “4th February Stone”.

Lucapa has a 40% stake in the Lulo mine. The rest is held by Angola’s national diamond company (Endiama) and Rosas & Petalas, a private entity.

Angola is the world’s fifth diamond producer by value and sixth by volume. Its industry, which began a century ago under Portuguese colonial rule, is successfully being liberalized.
