Wardite and Staurolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Wardite and Staurolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wardite and Staurolite Optical Properties during the identification of gemstone. Specific gravity of Wardite is 3.7-3.8 whereas that of Staurolite is 3.7-3.8.
