Kornerupine and Carnelian Specific Gravity
Another important criteria for qualitative analysis of gemstones is Kornerupine and Carnelian Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kornerupine and Carnelian Optical Properties during the identification of gemstone. Specific gravity of Kornerupine is 2.58-2.64 whereas that of Carnelian is 2.58-2.64.
