While comparing Andradite and Axinite 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 Axinite chemical formula.
Another important criteria for qualitative analysis of gemstones is Andradite and Axinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andradite and Axinite Optical Properties during the identification of gemstone. Specific gravity of Andradite is 3.26-3.36 whereas that of Axinite is 3.26-3.36.
