Diamond fracture and cleavage
WebCleavage is the tendency of a crystallised mineral to break in certain definite directions, giving more or less smooth surfaces. This splitting is due to weak cohesive forces … WebMinerals can form various shapes. Polygons are shown in Figure. The shapes form as the minerals are broken along their cleavage planes. Cleavage planes determine how the crystals can be cut to make smooth surfaces. People who cut gemstones follow cleavage planes. Diamonds and emeralds can be cut to make beautiful gemstones.

WebFracture Cleavage: In mineral terms, cleavage describes how a crystal breaks when subject to stress on a particular plane. If part of a crystal breaks due to stress and the … 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.
