Pyrophyllite and Actinolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrophyllite and Actinolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrophyllite and Actinolite Optical Properties during the identification of gemstone. Specific gravity of Pyrophyllite is 3.00 whereas that of Actinolite is 3.00.
