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

- Chemical formula of Omphacite- (Ca,Na)(Mg,Fe,Al)Si 2O 6Anthony et al , Handbook of Mineralogy (2001)
Chalcedony and Omphacite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chalcedony and Omphacite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chalcedony and Omphacite Optical Properties during the identification of gemstone. Specific gravity of Chalcedony is 3.16-3.43 whereas that of Omphacite is 3.16-3.43.
