Galena Cleavage
When it comes to choosing the best pick among Grey Gemstones gemstones, Galena is known to be a popular choice!Physical properties of Galena include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Galena 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. Galena cleavage is nothing but the plane across which the crystal splits during cutting. Galena cleavage is Cubic perfect on [001], parting on [111],and specific gravity of Galena is 6.23.
The physical properties of Galena, 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 Galena is represented by PbS.
