While comparing Ferro-axinite Axinite-Fe and Fibrolite 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 Ferro-axinite Axinite-Fe and Fibrolite chemical formula.
Another important criteria for qualitative analysis of gemstones is Ferro-axinite Axinite-Fe and Fibrolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ferro-axinite Axinite-Fe and Fibrolite Optical Properties during the identification of gemstone. Specific gravity of Ferro-axinite Axinite-Fe is 3.14-3.25 whereas that of Fibrolite is 3.14-3.25.
