Magnetite and Alexandrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Magnetite and Alexandrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnetite and Alexandrite Optical Properties during the identification of gemstone. Specific gravity of Magnetite is 3.69-3.81 whereas that of Alexandrite is 3.69-3.81.
