It was recovered earlier this week at the Letseng Mine, in Lesotho, a small kingdom in South Africa.<br /><br />The clarity and round shape of the new gem mean it could be worth considerably more than the previous find of the Letsing <span style="font-weight: bold;">"Promise" diamond </span>valued at 12.4 million a few months ago from the same mine.

Operated by De Beers between 1977 and 1982, Letšeng reopened operations in 2004 and was acquired by Gem Diamonds in 2006.<br /><br />The average elevation at the mine is 3,100m above mean sea level, making it the highest diamond mine in the world. The mine consists of two adjacent primary near vertical kimberlite pipes the Satellite and Main, with confirmed vertical depths of 495m and 655m respectively. The average grade of these resources is 1.72 carats per hundred tons (cpht). With approximately 14% of all stones being larger than 10.8 carats (ct), the production profile is more akin to that of an alluvial than kimberlite mine.<br /><br />The average price per carat achieved at Letšeng in 2007 was US$1 997 per ct, relative to an industry average of US$81 per ct. As such Letšeng is a remarkable mine producing some of the world’s remarkable diamonds including large gem quality diamonds that sell for the highest per carat price of any kimberlite mine.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjH2l5tGavYR5PEdQVJKkAfKKaJvH6pxad_qjhS_vC3WUrJuI91YVz-6oBnEhkLbbuhQw7oLM6zBDXz7848TZlFi_yeB4jbJOv6EG4B1kKQRQtS-xs6nAA7tqmc1BPXL9AdbMvymmVDOYav/s1600-h/Letseng+drilling+in+satellite+pipe+at+night.JPG" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" id="BLOGGER_PHOTO_ID_5248863368158888210" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjH2l5tGavYR5PEdQVJKkAfKKaJvH6pxad_qjhS_vC3WUrJuI91YVz-6oBnEhkLbbuhQw7oLM6zBDXz7848TZlFi_yeB4jbJOv6EG4B1kKQRQtS-xs6nAA7tqmc1BPXL9AdbMvymmVDOYav/s400/Letseng+drilling+in+satellite+pipe+at+night.JPG" style="cursor: pointer; width: 502px; height: 333px;" /></a><br />Above: drilling at night at the Letšeng' mine<br /><br />Historically 81% of Letšeng's revenue is from large diamonds (+10.8 ct) and 90% of the diamonds recovered are gem quality with a significant proportion graded as D colour.<br /><br />Some of the world's largest diamonds have been produced at Letšeng.
