Starlite and Anorthite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Starlite and Anorthite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Starlite and Anorthite Optical Properties during the identification of gemstone. Specific gravity of Starlite is 2.77 whereas that of Anorthite is 2.77.
