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

Moissanite and Astrophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moissanite and Astrophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Astrophyllite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 3.2-3.4 whereas that of Astrophyllite is 3.2-3.4.
