When it comes to choosing the best pick among Gems for Aquarius gemstones, Labradorite is known to be a popular choice!Physical properties of Labradorite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Labradorite 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. Labradorite cleavage is nothing but the plane across which the crystal splits during cutting. Labradorite cleavage is Perfect on , less perfect on , intersecting at near 90°; distinct on ,and specific gravity of Labradorite is 2.69-2.72.
The physical properties of Labradorite, 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 Labradorite is represented by (Na,Ca)1-2Si3-2O8.
