Chalcopyrite and Dioptase Chemical Formula
While comparing Chalcopyrite and Dioptase 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 Chalcopyrite and Dioptase chemical formula.

Chalcopyrite and Dioptase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chalcopyrite and Dioptase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chalcopyrite and Dioptase Optical Properties during the identification of gemstone. Specific gravity of Chalcopyrite is 3.25-3.35 whereas that of Dioptase is 3.25-3.35.
