Staurolite and Schorlomite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Staurolite and Schorlomite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Staurolite and Schorlomite Optical Properties during the identification of gemstone. Specific gravity of Staurolite is 3.77-3.93 whereas that of Schorlomite is 3.77-3.93.
