Elbaite and Lepidolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Elbaite and Lepidolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Elbaite and Lepidolite Optical Properties during the identification of gemstone. Specific gravity of Elbaite is 2.80-2.90 whereas that of Lepidolite is 2.80-2.90.
