Cryolite and Powellite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Powellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Powellite Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 4.23 whereas that of Powellite is 4.23.
