Chromite and Kornerupine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chromite and Kornerupine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chromite and Kornerupine Optical Properties during the identification of gemstone. Specific gravity of Chromite is 3.25-3.45 whereas that of Kornerupine is 3.25-3.45.
