Magnesite and Riebeckite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Magnesite and Riebeckite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnesite and Riebeckite Optical Properties during the identification of gemstone. Specific gravity of Magnesite is 3.28-3.44 whereas that of Riebeckite is 3.28-3.44.
