Elbaite and Unakite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Elbaite and Unakite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Elbaite and Unakite Optical Properties during the identification of gemstone. Specific gravity of Elbaite is 2.85-3.20 whereas that of Unakite is 2.85-3.20.
