Diamond fracture and cleavage
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. WebMay 5, 2016 · Even though diamond is the hardest natural material, it can chip and fracture in the course of normal wear. Diamond is formed in the cubic crystal system and has four perfect cleavage directions. A …
