While comparing Ametrine and Hibonite 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 Ametrine and Hibonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Ametrine and Hibonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ametrine and Hibonite Optical Properties during the identification of gemstone. Specific gravity of Ametrine is 3.84 whereas that of Hibonite is 3.84.
