When it comes to choosing the best pick among Green Gemstones gemstones, Verdelite is known to be a popular choice!Physical properties of Verdelite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Verdelite 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. Verdelite cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Verdelite is 2.90-3.40.
The physical properties of Verdelite, 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 Verdelite 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..
