Holmquistite Cleavage
When it comes to choosing the best pick among Black Gemstones gemstones, Holmquistite is known to be a popular choice!Physical properties of Holmquistite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Holmquistite 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. Holmquistite cleavage is nothing but the plane across which the crystal splits during cutting. Holmquistite cleavage is Perfect,and specific gravity of Holmquistite is 2.95-3.13.
The physical properties of Holmquistite, 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 Holmquistite is represented by Li 2[(Mg,Fe2+ ) 3Al 2]Si 8O 22(OH) 2Anthony et al , Handbook of mineralogy (2001).
