Polyhalite and Moroxite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Polyhalite and Moroxite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Polyhalite and Moroxite Optical Properties during the identification of gemstone. Specific gravity of Polyhalite is 3.13-3.26 whereas that of Moroxite is 3.13-3.26.
