Elbaite and Celestine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Elbaite and Celestine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Elbaite and Celestine Optical Properties during the identification of gemstone. Specific gravity of Elbaite is 3.90-4.00 whereas that of Celestine is 3.90-4.00.
