Africa focused miner Gem Diamonds has found yet another big precious stone at its prolific Letšeng mine in Lesotho, the third greater than 100 carat diamond mined in September.
The 212.91 carat Type II white diamond was recovered on September 19th, the company said on Monday. It is the thirteenth diamond over 100-carat unearthed this year at the operation, it noted.
Type IIa diamonds are the most valued and collectable precious gemstones, as they contain either very little or no nitrogen atoms in their crystal structure.
The Letšeng mine, owned 70% by Gem Diamonds, is one of the world’s ten largest diamond operations by revenue. At 3,100 metres (10,000 feet) above sea level, it is also one of the world’s most elevated diamond mines.
The operation has a track record of producing large, exceptional white diamonds, which makes it the highest-dollar-per-carat kimberlite diamond mine in the world.

Gem Diamonds has recovered a 117.47-carat rough from its Letšeng mine in Lesotho, its fourth over 100 carats so far this year.
The miner discovered the gem-quality, type IIa diamond on October 29, it said Tuesday. The find follows that of a 101.96-carat high-quality rough on September 28, and a 163.91-carat yellow diamond on June 22. The company also unearthed a 122-carat stone on March 5.
Letšeng has been known for producing high-quality rough diamonds topping the 100-carat mark, but recently that supply has been dwindling. However, the newest recovery brings this year’s total to a tie with last year, when the miner also retrieved four diamonds in that category. That compares with six in 2021 and 16 in 2020.
The declining number of special-size stones has put a dent in the company’s revenue, with sales falling 28% year on year to $71.8 million in the first six months of 2023. The miner incurred a loss of $1 million, versus a profit of $3.8 million during the same period in 2022.
