Elbaite and Edenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Elbaite and Edenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Elbaite and Edenite Optical Properties during the identification of gemstone. Specific gravity of Elbaite is 3.05-3.37 whereas that of Edenite is 3.05-3.37.
