Two big finds ex­ceed­ing 100 carat

The Star Early Edition - - COMPANIES -

GEM DI­A­MONDS dis­cov­ered two di­a­monds big­ger than 100 carats at its Le­sotho mine, bring­ing the strug­gling miner a step closer to end­ing a drought of large stones. Gem un­earthed a 104.73 carat D colour Type IIa di­a­mond and a 151.52 carat Type I yel­low di­a­mond at its Let­seng mine, the com­pany said yes­ter­day. Type IIa di­a­monds con­tain very lit­tle or no ni­tro­gen atoms and are the most ex­pen­sive stones. Un­til now Gem had re­ported just one large dis­cov­ery this year, af­ter un­earthing a 114 carat di­a­mond in April. Let­seng is renowned for the size and qual­ity of its stones, with an av­er­age sales price of al­most $2 000 (R25 818) a carat, the high­est in the in­dus­try. Yet the com­pany has suf­fered re­cently from a lack of big finds.
