When it comes to choosing the best pick among Blue Gemstones gemstones, Elbaite is known to be a popular choice!Physical properties of Elbaite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Elbaite 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. Elbaite cleavage is nothing but the plane across which the crystal splits during cutting. Elbaite cleavage is Poor/indistinct on and ,and specific gravity of Elbaite is 2.90-3.10.
The physical properties of Elbaite, 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 Elbaite is represented by Na(Li 1.5Al 1.5)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012) More from other references.
