Pyrophyllite and Quartz Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrophyllite and Quartz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrophyllite and Quartz Optical Properties during the identification of gemstone. Specific gravity of Pyrophyllite is 2.65 whereas that of Quartz is 2.65.
