Gem Diamonds has unearthed a 135-carat yellow from its Letšeng mine in Lesotho, making it the third major recovery of a colored diamond discovery from the mine this year. Gem recovered an exceptional, 134-carat Type I yellow diamond back in April - the first yellow stone of that magnitude since they dug up a 151.52-carat yellow diamond nearly two years ago.
In February, the miner also recovered a 13.33-carat pink diamond that they sold to Graff on tender in Antwerp for $8,750,360. The price for that stone set a new high on a dollar per carat basis for a Letšeng diamond, at $656,933. In the first half of 2019, Gem recovered only two stones greater than 100 carats as compared to 10 in the first half of 2018, which last year sent the miner on its way to recovering 15 stones larger than 100 carats, setting a record for a single year.
