Cleavage, Parting & Fracture (Physical Properties of Gemstone)

WebNote that no other mineral can scratch diamond. Cleavage and Fracture Breaking a mineral breaks its chemical bonds. Since some bonds are weaker than other bonds, each type of mineral is likely to break where the bonds between the atoms are weaker. For that reason, minerals break apart in characteristic ways. WebFracture and Cleavage. Fracture refers to rough or irregular surfaces along which the mineral breaks randomly. Cleavage refers to flat planes along which some minerals break. ...

WebLike fluorite, diamond also cleaves along four cleavage planes. Minerals described as having a 'perfect cleavage' cleave with an exceptionally clean break. Both edges and the new crystal faces that are created as a result of the break are smooth and flat. Cleavage surfaces always reflect light.
