Diaspore and Charoite Specific Gravity

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