When it comes to choosing the best pick among Red Gemstones gemstones, Cinnabar is known to be a popular choice!Physical properties of Cinnabar include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Cinnabar 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. Cinnabar cleavage is nothing but the plane across which the crystal splits during cutting. Cinnabar cleavage is Prismatic , perfect,and specific gravity of Cinnabar is 2.
The physical properties of Cinnabar, 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 Cinnabar is represented by HgSMichael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
