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

Wulfenite and Faustite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Wulfenite and Faustite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wulfenite and Faustite Optical Properties during the identification of gemstone. Specific gravity of Wulfenite is 2.9 whereas that of Faustite is 2.9.
