Cryolite and Magnesite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Magnesite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Magnesite Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 2.92-3.12 whereas that of Magnesite is 2.92-3.12.
