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