Phosphophyllite and Faustite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phosphophyllite and Faustite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosphophyllite and Faustite Optical Properties during the identification of gemstone. Specific gravity of Phosphophyllite is 2.9 whereas that of Faustite is 2.9.
