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

Augite and Jacobsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Augite and Jacobsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Augite and Jacobsite Optical Properties during the identification of gemstone. Specific gravity of Augite is 4.76-5.03 whereas that of Jacobsite is 4.76-5.03.
