Hauyne and Willemite Chemical Formula
While comparing Hauyne and Willemite 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 Hauyne and Willemite chemical formula.

Hauyne and Willemite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hauyne and Willemite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hauyne and Willemite Optical Properties during the identification of gemstone. Specific gravity of Hauyne is 3.89-4.18 whereas that of Willemite is 3.89-4.18.
