When it comes to choosing the best pick among Red Gemstones gemstones, Wulfenite is known to be a popular choice!Physical properties of Wulfenite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Wulfenite 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. Wulfenite cleavage is nothing but the plane across which the crystal splits during cutting. Wulfenite cleavage is On , distinct; on , , indistinct,and specific gravity of Wulfenite is 6.50-7.00.
The physical properties of Wulfenite, 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 Wulfenite is represented by PbMoO 4Walter Schumann , Gemstones of the world (2001).
