Brookite and Gyrolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Brookite and Gyrolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brookite and Gyrolite Optical Properties during the identification of gemstone. Specific gravity of Brookite is 2.48 whereas that of Gyrolite is 2.48.
