Omphacite and Beryllonite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Omphacite and Beryllonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Beryllonite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 2.79-2.87 whereas that of Beryllonite is 2.79-2.87.
