Periclase and Muscovite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Periclase and Muscovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Periclase and Muscovite Optical Properties during the identification of gemstone. Specific gravity of Periclase is 2.78-2.88 whereas that of Muscovite is 2.78-2.88.
