While comparing Andradite and Hauyne 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 Andradite and Hauyne chemical formula.
Another important criteria for qualitative analysis of gemstones is Andradite and Hauyne Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andradite and Hauyne Optical Properties during the identification of gemstone. Specific gravity of Andradite is 2.4-2.5 whereas that of Hauyne is 2.4-2.5.
