Cryolite and Turquoise Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Turquoise Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Turquoise Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 2.30-2.90 whereas that of Turquoise is 2.30-2.90.
