Staurolite and Morion Specific Gravity

Another important criteria for qualitative analysis of gemstones is Staurolite and Morion Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Staurolite and Morion Optical Properties during the identification of gemstone. Specific gravity of Staurolite is 2.65 whereas that of Morion is 2.65.
