Gem Diamonds has found a 129-carat rough stone at its Letšeng mine in Lesotho, the miner’s first one over 100 carats mined this year.
The high-quality white diamond was recovered at the site over the weekend, Gem Diamonds said. The company, known for the recovery of large, high-quality stones in 2020, has seen output of those diamonds become less frequent over the past year.
In 2021, Gem Diamonds found only six diamonds over 100 carats at Letšeng. This compares to 16 rocks of more than 100 carats discovered in 2020.
