When it comes to choosing the best pick among Gems Found In Africa gemstones, Hydrophane is known to be a popular choice!Physical properties of Hydrophane include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Hydrophane 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. Hydrophane cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Hydrophane is 1.98-2.50.
The physical properties of Hydrophane, 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 Hydrophane is represented by SiO 2 · nH 2OWalter Schumann , Gemstones of the world (2001).
