While comparing Bastnsite and Enstatite 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 Bastnsite and Enstatite chemical formula.
Another important criteria for qualitative analysis of gemstones is Bastnsite and Enstatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bastnsite and Enstatite Optical Properties during the identification of gemstone. Specific gravity of Bastnsite is 3.20-3.25 whereas that of Enstatite is 3.20-3.25.
