Moissanite and Anhydrite Chemical Formula

While comparing Moissanite and Anhydrite 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 Moissanite and Anhydrite chemical formula.

Moissanite and Anhydrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Anhydrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Anhydrite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 2.90-2.98 whereas that of Anhydrite is 2.90-2.98.
