Gem Diamonds unearths a 122 carat rough from its Letseng mine, in Lesotho, its first +100 carat of 2023.
Letšeng is known for producing a large supply of rough diamonds over 100 carats. However, the number of stones of that size has been declining over the years.
Last year, the mine retrieved only four diamonds of that calibre, compared to six in 2021 and 16 in 2020.
