Magnesite and Sunstone Specific Gravity

Another important criteria for qualitative analysis of gemstones is Magnesite and Sunstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnesite and Sunstone Optical Properties during the identification of gemstone. Specific gravity of Magnesite is 2.62-2.65 whereas that of Sunstone is 2.62-2.65.
