Rutile and Steatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rutile and Steatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rutile and Steatite Optical Properties during the identification of gemstone. Specific gravity of Rutile is 2.20-2.80 whereas that of Steatite is 2.20-2.80.
