While comparing Ludlamite and Boleite 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 Ludlamite and Boleite chemical formula.
Another important criteria for qualitative analysis of gemstones is Ludlamite and Boleite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ludlamite and Boleite Optical Properties during the identification of gemstone. Specific gravity of Ludlamite is 5.05 whereas that of Boleite is 5.05.
