Pyrite and Rhodolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrite and Rhodolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrite and Rhodolite Optical Properties during the identification of gemstone. Specific gravity of Pyrite is 3.84 whereas that of Rhodolite is 3.84.
