Aragonite and Rutile Specific Gravity

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