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

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