Anglesite and Foitite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anglesite and Foitite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anglesite and Foitite Optical Properties during the identification of gemstone. Specific gravity of Anglesite is 3.17 whereas that of Foitite is 3.17.
