Gem Diamonds on September 11 recovered a D-color, type II diamond weighing 127 carats from its Letšeng mine in Lesotho. The lastest find is the fourth exceptionally-sized (+100 carat) white diamond unearthed this year. Together with the three yellows stones larger than 100 carats recovered this year, their total of exceptional finds now sits at seven: the miner this year has recovered gem-quality white diamonds weighing 123.5, 127, 140 and 161 carats to go with gem-quality yellows weighing 114.2, 134 and 135 carats.
Last year the miner recovered 15 diamonds weighing more than 100 carats. The have attributed the decline in large, high-quality diamond recoveries to the "planned limited contribution from the satellite pipe ore," as they stated in thei publication of their first-half results. The satellite pipe is where Gem Diamonds recovers a higher percentage of high-quality diamonds at a higher grade than the main pipe, which is where they have mined a larger share of their ore so far this year.
