RAPAPORT… Gem Diamonds has recovered a 370-carat rough stone in Lesotho, the second over 100 carats in one week.
The “high-quality,” white, type II diamond came from the company’s Letšeng mine, known for producing large diamonds, it said Monday. The new find follows the discovery of a high-quality, 254-carat, white, type II diamond the miner reported on May 4.
The miner has unearthed three 100-carat-plus diamonds so far this year, including a 146.9-carat rough in January. Although output of large stones was sluggish in the first quarter as the company mined lower-value areas, it is still ahead of last year’s discovery of two stones greater than 100 carats by the middle of May.
In 2020, Gem Diamonds produced a total of 16 diamonds larger than 100 carats.
