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