Esperite and Moonstone Specific Gravity

Another important criteria for qualitative analysis of gemstones is Esperite and Moonstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Esperite and Moonstone Optical Properties during the identification of gemstone. Specific gravity of Esperite is 2.56-2.60 whereas that of Moonstone is 2.56-2.60.
