Sodalite and Phosgenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Phosgenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Phosgenite Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 6.13 whereas that of Phosgenite is 6.13.
