Pargasite and Pyrargyrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pargasite and Pyrargyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pargasite and Pyrargyrite Optical Properties during the identification of gemstone. Specific gravity of Pargasite is 5.85 whereas that of Pyrargyrite is 5.85.
