The most recent discovery concerns a white diamond, the statement said.
This gem "is the third of more than 100 carats recovered in Lulo block 46 in the last eight weeks, and the 19th of more than 100 carats found in the mine since operations began," the statement said.
Block 46 has produced, on average, "diamonds of more than 100 carats per 33,000 cubic meters of gravel processed, and is the block with the best indicators, even surpassing the prolific block 08," the note added.
The Lulo mine has been noted for its potential: rare and quality diamonds have been found here.
The largest diamond produced in the country originated from this mine. With 404 carats, this stone was discovered in 2016 and was subsequently sold for $16 million.
The mine is operated by the Lulo mining society, formed by Endiama, the Australian company Lucapa Diamond and Rosa e Pétalas.
The country produces between nine and 10 million carats annually.
