Cryolite and Scheelite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Scheelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Scheelite Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 5.9-6.3 whereas that of Scheelite is 5.9-6.3.
