When it comes to choosing the best pick among Green Gemstones gemstones, Ludlamite is known to be a popular choice!Physical properties of Ludlamite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Ludlamite 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. Ludlamite cleavage is nothing but the plane across which the crystal splits during cutting. Ludlamite cleavage is Vitreous, pearly on cleavage,and specific gravity of Ludlamite is 3.1-3.2.
The physical properties of Ludlamite, 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 Ludlamite is represented by (Fe2+ ,Mg,Mn2+ ) 3(PO 4) 2 · 4H 2OMichael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
