Brookite and Scolecite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Brookite and Scolecite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brookite and Scolecite Optical Properties during the identification of gemstone. Specific gravity of Brookite is 2.20-2.23 whereas that of Scolecite is 2.20-2.23.
