While comparing Staurolite and Mohawkite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Staurolite and Mohawkite chemical formula.
Another important criteria for qualitative analysis of gemstones is Staurolite and Mohawkite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Staurolite and Mohawkite Optical Properties during the identification of gemstone. Specific gravity of Staurolite is whereas that of Mohawkite is .
