Gem Diamonds has unearthed a 115-carat rough diamond, as the company’s shift to a more lucrative part of its Letšeng mine continues to yield an improvement in recoveries of large stones.

The D-color, type-IIa diamond is the sixth stone above 100 carats that Gem Diamonds has found this year at its high-value mine in Lesotho. In 2016, the miner only recovered five diamonds of this size, resulting in a 22% drop in revenue.

In the second quarter of this year, the company switched focus to the higher-grade K6 portion of Letšeng’s main pipe, enabling a higher recovery rate of large diamonds.
