Pyrophyllite and Glass Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyrophyllite and Glass Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrophyllite and Glass Optical Properties during the identification of gemstone. Specific gravity of Pyrophyllite is 2.39-4.00 whereas that of Glass is 2.39-4.00.
