Steatite and Grandidierite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Steatite and Grandidierite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Steatite and Grandidierite Optical Properties during the identification of gemstone. Specific gravity of Steatite is 2.85-3.00 whereas that of Grandidierite is 2.85-3.00.
