Kornerupine and Realgar Specific Gravity
Another important criteria for qualitative analysis of gemstones is Kornerupine and Realgar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kornerupine and Realgar Optical Properties during the identification of gemstone. Specific gravity of Kornerupine is 3.56 whereas that of Realgar is 3.56.
