Moissanite and Spodumene Chemical Formula
While comparing Moissanite and Spodumene 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 Spodumene chemical formula.

Moissanite and Spodumene Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moissanite and Spodumene Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Spodumene Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 3.15-3.21 whereas that of Spodumene is 3.15-3.21.
