Diamond is a valuable stone that is made up of a characteristically colorless and clear crystalline type of uncontaminated carbon (Koizumi, Nebel and Nesladek 3). According to Pagel-Theisen (6), the diamond may also be defined as a really hard form of carbon that is greatly refractive. The stone, which is normally used as a gemstone, is usually colorless. In terms of mineral hardness, diamond is considered the hardest known natural object.
