Cryolite and Uvarovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cryolite and Uvarovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Uvarovite Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 3.77 whereas that of Uvarovite is 3.77.
