Steatite and Pumpellyite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Steatite and Pumpellyite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Steatite and Pumpellyite Optical Properties during the identification of gemstone. Specific gravity of Steatite is 3.20-3.30 whereas that of Pumpellyite is 3.20-3.30.
