While comparing Charlesite and Moissanite 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 Charlesite and Moissanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Charlesite and Moissanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Charlesite and Moissanite Optical Properties during the identification of gemstone. Specific gravity of Charlesite is 3.17-3.24 whereas that of Moissanite is 3.17-3.24.
