Zoisite and Magnetite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Zoisite and Magnetite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zoisite and Magnetite Optical Properties during the identification of gemstone. Specific gravity of Zoisite is 5.2 whereas that of Magnetite is 5.2.
