When it comes to choosing the best pick among Green Gemstones gemstones, Hemimorphite is known to be a popular choice!Physical properties of Hemimorphite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Hemimorphite 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. Hemimorphite cleavage is nothing but the plane across which the crystal splits during cutting. Hemimorphite cleavage is Perfect on , poor on , rare,and specific gravity of Hemimorphite is 3.30-3.50.
The physical properties of Hemimorphite, 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 Hemimorphite is represented by Zn 4Si 2O 7(OH) 2H 2OMichael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
