When it comes to choosing the best pick among Yellow Gemstones gemstones, Legrandite is known to be a popular choice!Physical properties of Legrandite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Legrandite 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. Legrandite cleavage is nothing but the plane across which the crystal splits during cutting. Legrandite cleavage is Imperfect, poor one ,and specific gravity of Legrandite is 3.98-4.04.
The physical properties of Legrandite, 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 Legrandite is represented by Zn 2(AsO 4)(OH) · H 2OMichael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
