Periclase and Barite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Periclase and Barite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Periclase and Barite Optical Properties during the identification of gemstone. Specific gravity of Periclase is 4.48 whereas that of Barite is 4.48.
