Lucapa Diamond Company has recovered a 160-carat, high-quality rough from its Lulo mine in Angola, the sixth-largest stone the deposit has yielded.
The company found the type IIa diamond at the same alluvial mining block from which it unearthed a 170-carat pink — the Lulo Rose — in July, Lucapa said last week. The new addition marks the 28th diamond over 100 carats from Lulo.
Recently, Lucapa transitioned to mining rough from the lezirias, or flood plain area, of the site, which has led to the recovery of larger diamonds, it said. In the past two months, the miner has found more than 100 special stones — those weighing over 10.8 carats — at the deposit, including four type IIa rough diamonds weighing 99, 81, 74 and 66 carats.
