Magnesite and Brookite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Magnesite and Brookite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnesite and Brookite Optical Properties during the identification of gemstone. Specific gravity of Magnesite is 3.87-4.14 whereas that of Brookite is 3.87-4.14.
