When it comes to choosing the best pick among Green Gemstones gemstones, Chlorapatite is known to be a popular choice!Physical properties of Chlorapatite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Chlorapatite 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. Chlorapatite cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Chlorapatite is 3.17-3.18.
The physical properties of Chlorapatite, 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 Chlorapatite is represented by Ca 5(PO 4) 3ClAnthony et al , Handbook of mineralogy (2001).
