Pyrophyllite and Cerussite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrophyllite and Cerussite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrophyllite and Cerussite Optical Properties during the identification of gemstone. Specific gravity of Pyrophyllite is 6.46-6.57 whereas that of Cerussite is 6.46-6.57.
