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