Pyrargyrite and Povondraite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyrargyrite and Povondraite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrargyrite and Povondraite Optical Properties during the identification of gemstone. Specific gravity of Pyrargyrite is 3.26 whereas that of Povondraite is 3.26.
