While comparing Fluor buergerite and Kyanite 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 Fluor buergerite and Kyanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Fluor buergerite and Kyanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluor buergerite and Kyanite Optical Properties during the identification of gemstone. Specific gravity of Fluor buergerite is 3.53-3.65 whereas that of Kyanite is 3.53-3.65.
