Esperite and Charoite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Esperite and Charoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Esperite and Charoite Optical Properties during the identification of gemstone. Specific gravity of Esperite is 2.54-2.78 whereas that of Charoite is 2.54-2.78.
