摘要：Since the late 1960s, it has been known that pink and redcorundum occur in the area near Fiskenæsset (Qeqertarsuatsiaat)in southern West Greenland. Corundum is hosted inthe Fiskenæsset complex, which is part of the Archaean basementof the North Atlantic Craton. To date, c. 40 corundumlocalities with a wide range of quality are known in the area– a few localities yield stones of gem quality. The most promisinglocality, Aappaluttoq, is likely to be mined in the foreseeablefuture by the Canadian company True North Gems(Figs 1, 2A). Red corundum of gem quality is called ruby;gem quality corundum of other colours (e.g. pink, yellow orblue) is called pink sapphire, yellow sapphire etc., while theblue gem corundum is sapphire. Red, pink and blue corundumare also known in smaller quantities from other areasin Greenland.
