Moroxite and Chromite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moroxite and Chromite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moroxite and Chromite Optical Properties during the identification of gemstone. Specific gravity of Moroxite is 4.5-4.8 whereas that of Chromite is 4.5-4.8.
