Spinel and Magnesite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spinel and Magnesite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spinel and Magnesite Optical Properties during the identification of gemstone. Specific gravity of Spinel is 2.92-3.12 whereas that of Magnesite is 2.92-3.12.
