Periclase and Quartz Specific Gravity

Another important criteria for qualitative analysis of gemstones is Periclase and Quartz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Periclase and Quartz Optical Properties during the identification of gemstone. Specific gravity of Periclase is 2.65 whereas that of Quartz is 2.65.
