Moissanite and Calcite Chemical Formula

While comparing Moissanite and Calcite 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 Calcite chemical formula.

Moissanite and Calcite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
