Sodalite and Violane Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Violane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Violane Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 3.22-3.40 whereas that of Violane is 3.22-3.40.
