When it comes to choosing the best pick among Blue Gemstones gemstones, Gahnite is known to be a popular choice!Physical properties of Gahnite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Gahnite 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. Gahnite cleavage is nothing but the plane across which the crystal splits during cutting. Gahnite cleavage is Indistinct parting on [111],and specific gravity of Gahnite is 4.00-4.62.
The physical properties of Gahnite, 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 Gahnite is represented by ZnAl 2O 4Michael OâDonoghue , Gems, Sixth Edition (2006).
