When it comes to choosing the best pick among Gems Found in South Asia gemstones, Achroite is known to be a popular choice!Physical properties of Achroite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Achroite 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. Achroite cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Achroite is 2.90-3.40.
The physical properties of Achroite, 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 Achroite 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) Formula given for elbaite..
