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