When it comes to choosing the best pick among Blue Gemstones gemstones, Anhydrite is known to be a popular choice!Physical properties of Anhydrite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Anhydrite 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. Anhydrite cleavage is nothing but the plane across which the crystal splits during cutting. Anhydrite cleavage is Rare tabular and prismatic crystals. Usually occurs as fibrous, parallel veins that break off into cleavage fragments.,and specific gravity of Anhydrite is 2.90-2.98.
The physical properties of Anhydrite, 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 Anhydrite is represented by CaSO 4Michael OâDonoghue , Gems, Sixth edition (2006) More from other references.
