Sodalite and Smithsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Smithsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Smithsonite Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 4.00-4.65 whereas that of Smithsonite is 4.00-4.65.
