While comparing Magnesio axinite Axinite Mg and Sillimanite 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 Magnesio axinite Axinite Mg and Sillimanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Magnesio axinite Axinite Mg and Sillimanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnesio axinite Axinite Mg and Sillimanite Optical Properties during the identification of gemstone. Specific gravity of Magnesio axinite Axinite Mg is 3.20-3.26 whereas that of Sillimanite is 3.20-3.26.
