When it comes to choosing the best pick among Blue Gemstones gemstones, Gahnospinel is known to be a popular choice!Physical properties of Gahnospinel include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Gahnospinel 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. Gahnospinel cleavage is nothing but the plane across which the crystal splits during cutting. Gahnospinel cleavage is None, but may exhibit slight parting,and specific gravity of Gahnospinel is 3.65-4.55.
The physical properties of Gahnospinel, 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 Gahnospinel is represented by (Mg,Zn)Al 2O 4Gemdat.org , Management Team (2012).
