Magnetite and Amethyst Specific Gravity

Another important criteria for qualitative analysis of gemstones is Magnetite and Amethyst Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnetite and Amethyst Optical Properties during the identification of gemstone. Specific gravity of Magnetite is 2.65 whereas that of Amethyst is 2.65.
