While comparing Andradite and Kutnohorite 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 Kutnohorite chemical formula.
Another important criteria for qualitative analysis of gemstones is Andradite and Kutnohorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andradite and Kutnohorite Optical Properties during the identification of gemstone. Specific gravity of Andradite is 3.12 whereas that of Kutnohorite is 3.12.
