Omphacite and Elbaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Omphacite and Elbaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Elbaite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 2.90-3.10 whereas that of Elbaite is 2.90-3.10.
