Starlite and Verdite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Starlite and Verdite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Starlite and Verdite Optical Properties during the identification of gemstone. Specific gravity of Starlite is 2.80-3.0 whereas that of Verdite is 2.80-3.0.
