Diamond is the hardest known mineral of natural origin, which makes it an excellent abrasive. To obtain cut diamonds, it is only possible to treat them under high pressure and high temperature with other diamonds (known as Type-II diamonds) that are harder or with substances that are harder than the diamond itself. These substances may be borazone, ultra-hard fullerite or diamond nanostat. It also means that the diamond retains its surface polish perfectly - its excellent luster. The melting point of diamond is 3547 ° C - the highest of all minerals.
