When it comes to choosing the best pick among Red Gemstones gemstones, Cassiterite is known to be a popular choice!Physical properties of Cassiterite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Cassiterite 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. Cassiterite cleavage is nothing but the plane across which the crystal splits during cutting. Cassiterite cleavage is imperfect, indistinct; partings on or ,and specific gravity of Cassiterite is 6.86-7.03.
The physical properties of Cassiterite, 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 Cassiterite is represented by SnO 2Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
