Moissanite and Goethite Chemical Formula

While comparing Moissanite and Goethite 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 Goethite chemical formula.

Moissanite and Goethite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Goethite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Goethite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 4.27-4.29 whereas that of Goethite is 4.27-4.29.
