Eosphorite and Cryolite Specific Gravity

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