Letšeng Mine finds a 254ct Rough

Gem Diamonds has found a high quality 254 carat Type II white gem at its Letšeng mine in Lesotho, the highest dollar per carat diamond mine in the world.

The “high-quality,” type II, white diamond came from the company’s lucrative Letšeng mine, it said in a statement Tuesday.

The miner had not publicized any noteworthy finds since January, when the deposit produced a 146.9-carat rough. Output of large diamonds was sluggish in the first quarter because of the nature of the areas of Letšeng the company accessed during the quarter, CEO Clifford Elphick said last month.
