Sodalite and Aragonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Aragonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Aragonite Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 2.93-2.96 whereas that of Aragonite is 2.93-2.96.
