Sunstone and Rock Crystal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sunstone and Rock Crystal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Rock Crystal Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 2.65 whereas that of Rock Crystal is 2.65.
