In a statement posted on its official website, the Australian Lucapa Diamond Company reveals that this sample "represents the largest number of diamonds recovered from any kimberlite sample in the Canguige area so far".
It adds that the 13 diamonds have a total weight of 4.15 carats and that, of the total stones discovered, eight are defined as rare because they are defined as 'Type IIa'.
The company considered this discovery to be a "significant result", as 'Type IIa' diamonds "form less than two percent of the global production of natural rough diamonds", being "in demand because of their color, quality and size".
According to the note, the largest gemstone recovered "was a 0.93 carat white diamond" and the largest 'Type IIa' type diamond recovered weighs 0.59 carats.
Stephen Wetherall, the company's CEO, said "this is a particularly important result."
Remember that the largest diamond produced in the country originated in this mine. With 404 carats, the stone was discovered in 2016, and was later sold for 16 million dollars.
The mine is operated by the Lulo mining company, formed by Endiama, the Australian company Lucapa Diamond and Rosa e Pétalas.
