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

Omphacite and Chalcopyrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Omphacite and Chalcopyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Chalcopyrite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 4.1-4.3 whereas that of Chalcopyrite is 4.1-4.3.
