Brookite and Microcline Specific Gravity
Another important criteria for qualitative analysis of gemstones is Brookite and Microcline Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brookite and Microcline Optical Properties during the identification of gemstone. Specific gravity of Brookite is 2.55-2.63 whereas that of Microcline is 2.55-2.63.
