Wulfenite and Moissanite Chemical Formula

While comparing Wulfenite 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 Wulfenite and Moissanite chemical formula.

Wulfenite and Moissanite Specific Gravity

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