Clinohumite and Sodalite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Clinohumite and Sodalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinohumite and Sodalite Optical Properties during the identification of gemstone. Specific gravity of Clinohumite is 2.15-2.40 whereas that of Sodalite is 2.15-2.40.
