When it comes to choosing the best pick among Colorless Gems gemstones, Taaffeite is known to be a popular choice!Physical properties of Taaffeite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Taaffeite 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. Taaffeite cleavage is nothing but the plane across which the crystal splits during cutting. Taaffeite cleavage is Imperfect/fair/absent,and specific gravity of Taaffeite is 3.60-3.61.
The physical properties of Taaffeite, 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 Taaffeite is represented by Mg 3Al 8BeO 16Walter Schumann , Gemstones of the world (2001) More from other references.
