Elbaite and Agate Specific Gravity

Another important criteria for qualitative analysis of gemstones is Elbaite and Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Elbaite and Agate Optical Properties during the identification of gemstone. Specific gravity of Elbaite is 2.60-2.64 whereas that of Agate is 2.60-2.64.
