Pyrophyllite and Scapolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyrophyllite and Scapolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrophyllite and Scapolite Optical Properties during the identification of gemstone. Specific gravity of Pyrophyllite is 2.58-2.74 whereas that of Scapolite is 2.58-2.74.
