Phosgenite and Calcite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Phosgenite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosgenite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Phosgenite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
