Elbaite and Gyrolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Elbaite and Gyrolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Elbaite and Gyrolite Optical Properties during the identification of gemstone. Specific gravity of Elbaite is 2.48 whereas that of Gyrolite is 2.48.
