Epidote and Allanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Epidote and Allanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Epidote and Allanite Optical Properties during the identification of gemstone. Specific gravity of Epidote is 3.40-4.20 whereas that of Allanite is 3.40-4.20.
