When it comes to choosing the best pick among Gems for Virgo gemstones, Zircon is known to be a popular choice!Physical properties of Zircon include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Zircon 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. Zircon cleavage is nothing but the plane across which the crystal splits during cutting. Zircon cleavage is and ,and specific gravity of Zircon is 3.93-4.73.
The physical properties of Zircon, 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 Zircon is represented by ZrSiO4.
