Corundum and Garnet Specific Gravity
Another important criteria for qualitative analysis of gemstones is Corundum and Garnet Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Corundum and Garnet Optical Properties during the identification of gemstone. Specific gravity of Corundum is 3.55-4.33 whereas that of Garnet is 3.55-4.33.
