Hyalite and Glass Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hyalite and Glass Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hyalite and Glass Optical Properties during the identification of gemstone. Specific gravity of Hyalite is 2.39-4.00 whereas that of Glass is 2.39-4.00.
