Achroite and Schorlomite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Achroite and Schorlomite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Achroite and Schorlomite Optical Properties during the identification of gemstone. Specific gravity of Achroite is 3.77-3.93 whereas that of Schorlomite is 3.77-3.93.
