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

Augite and Chalcedony Specific Gravity
Another important criteria for qualitative analysis of gemstones is Augite and Chalcedony Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Augite and Chalcedony Optical Properties during the identification of gemstone. Specific gravity of Augite is 2.55-2.70 whereas that of Chalcedony is 2.55-2.70.
