Periclase and Fibrolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Periclase and Fibrolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Periclase and Fibrolite Optical Properties during the identification of gemstone. Specific gravity of Periclase is 3.14-3.25 whereas that of Fibrolite is 3.14-3.25.
