Gaspeite and Achroite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gaspeite and Achroite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gaspeite and Achroite Optical Properties during the identification of gemstone. Specific gravity of Gaspeite is 2.90-3.40 whereas that of Achroite is 2.90-3.40.
