When it comes to choosing the best pick among Yellow Gemstones gemstones, Diaspore is known to be a popular choice!Physical properties of Diaspore include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Diaspore 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. Diaspore cleavage is nothing but the plane across which the crystal splits during cutting. Diaspore cleavage is perfect, distinct, in traces,and specific gravity of Diaspore is 3.30-3.40.
The physical properties of Diaspore, 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 Diaspore is represented by AlO(OH)Walter Schumann , Gemstones of the world (2001) More from other references.
