Geographic typing of gem corundum: a test case from Australia

F. Lin Sutherland, Ahmadjan Abduriyim

A group of analysed sapphires attributed to the rather broad source region of New South Wales was investigated by comparison of their trace element contents with those of sapphires from known Australian fields. Both groups of sapphires were analysed using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) at the same Japanese laboratory. Blue sapphires from Anakie, Queensland, were included for comparison as these are also sold in New South Wales. Comparisons of Fe, Ti, Mg,
more » ... Cr, Ga and other trace element contents suggest that the vaguely located group of sapphires came from the Inverell gem field in New England. The results give encouragement for more studies on geographic typing of gem corundum.
