Hanksite and Starlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hanksite and Starlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hanksite and Starlite Optical Properties during the identification of gemstone. Specific gravity of Hanksite is 3.91-4.73 whereas that of Starlite is 3.91-4.73.
