Uvarovite and Periclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Uvarovite and Periclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvarovite and Periclase Optical Properties during the identification of gemstone. Specific gravity of Uvarovite is 3.7-3.9 whereas that of Periclase is 3.7-3.9.
