Botswana mine yields 342-carat diamond

Lucara Diamond Corp. announced this week the discovery of a 341.9-carat gem-quality diamond at its Karowe Mine in Botswana, the same mine that yielded two 200-carat-plus pieces of rough last year. 
The diamond is a Type IIa that shows “exceptional color and clarity”. It will be sold along with two other big pieces of rough, both of which are more than 100 carats. The sale date has yet to be determined.
The diamond was found while processing fragmental kimberlite from the central and south lobe interface of the mine, which is proving, somewhat surprisingly, to be a prolific source of high-quality, large rough diamonds.

Exceptional 63.05-carat Diamond Found

Lucapa Diamond Company recovered an “exceptional” 63.05-carat, Type IIa diamond from its alluvial mining operations at the Lulo Diamond Concession in Angola. It is the biggest diamond recovered since Lucapa started commercial mining operations at the site in January and the company’s third-largest stone unearthed at Lulo, behind 131.40-carat and 95.45-carat stones (both of which also were Type IIa).
