Magnetite and Andalusite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Magnetite and Andalusite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnetite and Andalusite Optical Properties during the identification of gemstone. Specific gravity of Magnetite is 3.05-3.21 whereas that of Andalusite is 3.05-3.21.
