Cryolite and Chrysocolla Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Chrysocolla Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Chrysocolla Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 2.00-2.45 whereas that of Chrysocolla is 2.00-2.45.
