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

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