Magnesite and Diaspore Specific Gravity

Another important criteria for qualitative analysis of gemstones is Magnesite and Diaspore Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnesite and Diaspore Optical Properties during the identification of gemstone. Specific gravity of Magnesite is 3.30-3.40 whereas that of Diaspore is 3.30-3.40.
