Brookite and Hibschite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Brookite and Hibschite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brookite and Hibschite Optical Properties during the identification of gemstone. Specific gravity of Brookite is 3.05-3.08 whereas that of Hibschite is 3.05-3.08.
