Staurolite and Dioptase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Staurolite and Dioptase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Staurolite Vs Dioptase during the identification of gemstone. Specific gravity of Staurolite is whereas that of Dioptase is .
