Star Diamond Corporation confirms high proportions of Type IIa diamonds in both the Star and the Orion South kimberlites

06 march 2019

star_diamond_logo.pngGeorge H. Read, Senior Vice President Exploration and Development of Star Diamond Corporation announced that the Corporation has completed a major study into the abundance of Type IIa diamonds in the diamond parcels recovered from the Star and Orion South Kimberlites located within the Corporation’s Star - Orion South Diamond Project, in the Fort à la Corne diamond district of central Saskatchewan, Canada, on mineral dispositions held 100 percent by Star Diamond.
This study confirms that unusually high proportions of Type IIa diamonds are present in both the Star (26.5 percent) and the Orion South (12.5 percent) kimberlites.
Type IIa diamonds are very rare and account for approximately less than 2 percent of all natural rough diamonds mined from kimberlites. Only a small number of active diamond mines regularly produce Type IIa diamonds with the most important of these mines being Letseng-la-Terae (Letseng Mine) in the Kingdom of Lesotho.
The 2010 study on plus 2.7 carat diamonds from Star demonstrates that the Star Kimberlite has a similar proportion of Type IIa diamonds to Letseng. The largest Type IIa diamonds identified include a 49.09 carat stone from Star and a 32.35 carat stone from Orion South. The most valuable of the Type IIa diamonds from Star is the 11.96 carat diamond valued at US$11,333 per carat and the most valuable of the Type IIa diamonds from Orion South is the 15.88 carat diamond valued at US$2,800 per carat.
