While comparing Mottramite and Clintonite 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 Mottramite and Clintonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Mottramite and Clintonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Mottramite and Clintonite Optical Properties during the identification of gemstone. Specific gravity of Mottramite is 3.0-3.1 whereas that of Clintonite is 3.0-3.1.
