Hardystonite and Rutile Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hardystonite and Rutile Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hardystonite and Rutile Optical Properties during the identification of gemstone. Specific gravity of Hardystonite is 4.20-4.30 whereas that of Rutile is 4.20-4.30.
