Pyrite and Hackmanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyrite and Hackmanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrite and Hackmanite Optical Properties during the identification of gemstone. Specific gravity of Pyrite is 2.27-2.33 whereas that of Hackmanite is 2.27-2.33.
