Shigaite and Moissanite Chemical Formula

While comparing Shigaite 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 Shigaite and Moissanite chemical formula.

Shigaite and Moissanite Specific Gravity

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