It is a giant molecule of carbon atom is linked to four other carbon atoms by strong covalent bonds forming a rigid three-dimensional network structure, which is responsible for its hardness. Moreover, a lot of energy is required to break the network of strong covalent bonds in the diamond crystal, thus its melting point is very high.
• Due to its hardness it is used as knives for cutting marble, granite and glass.
