Schorl and Brookite Specific Gravity

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