While comparing Clinothulite and Vesuvianite 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 Clinothulite and Vesuvianite chemical formula.
Another important criteria for qualitative analysis of gemstones is Clinothulite and Vesuvianite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinothulite and Vesuvianite Optical Properties during the identification of gemstone. Specific gravity of Clinothulite is 3.32-3.43 whereas that of Vesuvianite is 3.32-3.43.
