Grandidierite Cleavage
When it comes to choosing the best pick among Green Gemstones gemstones, Grandidierite is known to be a popular choice!Physical properties of Grandidierite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Grandidierite 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. Grandidierite cleavage is nothing but the plane across which the crystal splits during cutting. Grandidierite cleavage is Perfect,and specific gravity of Grandidierite is 2.85-3.00.
The physical properties of Grandidierite, 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 Grandidierite is represented by (Mg,Fe)Al 3(BO 4)(SiO 4)OUlrich Henn and Claudio C..
