When it comes to choosing the best pick among Gems for Gemini gemstones, Lazulite is known to be a popular choice!Physical properties of Lazulite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Lazulite 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. Lazulite cleavage is nothing but the plane across which the crystal splits during cutting. Lazulite cleavage is Indistinct, Indistinct,and specific gravity of Lazulite is 3.04-3.17.
The physical properties of Lazulite, 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 Lazulite is represented by (Mg,Fe)Al 2(PO 4) 2(OH) 2Arthur Thomas , Gemstones (2009) More from other references.
