Pyrophyllite and Thaumasite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyrophyllite and Thaumasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrophyllite and Thaumasite Optical Properties during the identification of gemstone. Specific gravity of Pyrophyllite is 1.91 whereas that of Thaumasite is 1.91.
