Glass and Cryolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Glass and Cryolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Glass and Cryolite Optical Properties during the identification of gemstone. Specific gravity of Glass is 2.97 whereas that of Cryolite is 2.97.
