Periclase and Topazolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Periclase and Topazolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Periclase and Topazolite Optical Properties during the identification of gemstone. Specific gravity of Periclase is 3.70-4.10 whereas that of Topazolite is 3.70-4.10.
