Pyrargyrite and Brookite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyrargyrite and Brookite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrargyrite and Brookite Optical Properties during the identification of gemstone. Specific gravity of Pyrargyrite is 3.87-4.14 whereas that of Brookite is 3.87-4.14.
