When it comes to choosing the best pick among Blue Gemstones gemstones, Dravite is known to be a popular choice!Physical properties of Dravite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Dravite Optical Properties are responsible for imparting various physical properties to its structure. Knowledge of these properties is equally important to gem-cutters as well as to consumers. Dravite cleavage is nothing but the plane across which the crystal splits during cutting. Dravite cleavage is Indistinct,and specific gravity of Dravite is 3.03-3.18.
The physical properties of Dravite, in fact, are imparted by the chemical composition of its individual molecule. The reactivity or inertness of the crystal is solely governed by its chemical structure. Chemical composition of Dravite is represented by Na(Mg 3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012).
