Phosgenite and Sard Specific Gravity

Another important criteria for qualitative analysis of gemstones is Phosgenite and Sard Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosgenite and Sard Optical Properties during the identification of gemstone. Specific gravity of Phosgenite is 2.58-2.63 whereas that of Sard is 2.58-2.63.
