Celestine Cleavage
When it comes to choosing the best pick among Gems for Gemini gemstones, Celestine is known to be a popular choice!Physical properties of Celestine include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Celestine 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. Celestine cleavage is nothing but the plane across which the crystal splits during cutting. Celestine cleavage is Perfect on , good on , poor on ,and specific gravity of Celestine is 3.90-4.00.
The physical properties of Celestine, 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 Celestine is represented by SrSO 4Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
