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

Jadeite and Omphacite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jadeite and Omphacite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jadeite and Omphacite Optical Properties during the identification of gemstone. Specific gravity of Jadeite is 3.16-3.43 whereas that of Omphacite is 3.16-3.43.
