Powellite and Corundum Specific Gravity
Another important criteria for qualitative analysis of gemstones is Powellite and Corundum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Powellite and Corundum Optical Properties during the identification of gemstone. Specific gravity of Powellite is 3.90-4.05 whereas that of Corundum is 3.90-4.05.
