Moonstone and Chromite Specific Gravity

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