Ettringite Cleavage
When it comes to choosing the best pick among Yellow Gemstones gemstones, Ettringite is known to be a popular choice!Physical properties of Ettringite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Ettringite 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. Ettringite cleavage is nothing but the plane across which the crystal splits during cutting. Ettringite cleavage is Perfect on ,and specific gravity of Ettringite is 1.77.
The physical properties of Ettringite, 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 Ettringite is represented by Ca 6Al 2(SO 4) 3(OH) 12 26H 2OMichael OâDonoghue , Gems, Sixth Edition (2006).
