Sunstone and Sapphirine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sunstone and Sapphirine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Sapphirine Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 3.40-3.58 whereas that of Sapphirine is 3.40-3.58.
