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