Augite and Augelite Chemical Formula
While comparing Augite and Augelite 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 Augite and Augelite chemical formula.

Augite and Augelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Augite and Augelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Augite and Augelite Optical Properties during the identification of gemstone. Specific gravity of Augite is 2.70-2.75 whereas that of Augelite is 2.70-2.75.
