Omphacite and Uvarovite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Omphacite and Uvarovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Uvarovite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 3.77 whereas that of Uvarovite is 3.77.
