Periclase and Diopside Specific Gravity

Another important criteria for qualitative analysis of gemstones is Periclase and Diopside Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Periclase and Diopside Optical Properties during the identification of gemstone. Specific gravity of Periclase is 3.22-3.40 whereas that of Diopside is 3.22-3.40.
