Alexandrite and Magnetite Specific Gravity

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