Charoite and Phlogopite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Charoite and Phlogopite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Charoite and Phlogopite Optical Properties during the identification of gemstone. Specific gravity of Charoite is 2.78-2.85 whereas that of Phlogopite is 2.78-2.85.
