When it comes to choosing the best pick among Red Gemstones gemstones, Alunite is known to be a popular choice!Physical properties of Alunite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Alunite 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. Alunite cleavage is nothing but the plane across which the crystal splits during cutting. Alunite cleavage is On , perfect,and specific gravity of Alunite is 2.6-2.9.
The physical properties of Alunite, 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 Alunite is represented by KAl3(SO4)2(OH)6.
