Moissanite and Chromite Chemical Formula

While comparing Moissanite and Chromite 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 Chromite chemical formula.

Moissanite and Chromite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Chromite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Chromite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 4.5-4.8 whereas that of Chromite is 4.5-4.8.
