Charoite and Colemanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Charoite and Colemanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Charoite and Colemanite Optical Properties during the identification of gemstone. Specific gravity of Charoite is 2.40-2.42 whereas that of Colemanite is 2.40-2.42.
