Gem Diamonds has recovered a 135 carat yellow at its Letšeng mine in Lesotho, the third significant colored-diamond discovery at the deposit this year.
The company retrieved the high quality, type I stone on June 21, three months after the mine yielded a similar quality yellow diamond weighing 134 carats. Those discoveries follow a two year gap in the recovery of yellow diamonds weighing more than 100 carats from Letšeng. In June 2017, the miner found a 151.52 carat yellow.
