Diamond fracture and cleavage

WebThe hardest known mineral, diamond is pure carbon. Its crystals typically occur as octahedrons and cubes with rounded edges and slightly convex faces. Crystals may be transparent, translucent, or opaque. They range … 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.
