Brookite and Humite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Brookite and Humite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brookite and Humite Optical Properties during the identification of gemstone. Specific gravity of Brookite is 3.20-3.32 whereas that of Humite is 3.20-3.32.
