Pyrophyllite and Inderite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyrophyllite and Inderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrophyllite and Inderite Optical Properties during the identification of gemstone. Specific gravity of Pyrophyllite is 1.79 whereas that of Inderite is 1.79.
