When it comes to choosing the best pick among Gems Found in USA gemstones, Ulexite is known to be a popular choice!Physical properties of Ulexite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Ulexite 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. Ulexite cleavage is nothing but the plane across which the crystal splits during cutting. Ulexite cleavage is Perfect, Perfect,and specific gravity of Ulexite is 1.65-1.99.
The physical properties of Ulexite, 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 Ulexite is represented by NaCaB 5O 6(OH) 6 · 5H 2OMichael OâDonoghue , Gems, Sixth Edition (2006).
