When it comes to choosing the best pick among Brown Gemstones gemstones, Epidote is known to be a popular choice!Physical properties of Epidote include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Epidote 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. Epidote cleavage is nothing but the plane across which the crystal splits during cutting. Epidote cleavage is perfect and imperfect,and specific gravity of Epidote is 3.25-3.50.
The physical properties of Epidote, 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 Epidote is represented by CaAl 2(Fe3+ ,Al)Si 3O 12(OH)Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
