 A brilliant is a polished diamond. Diamond is the hardest known natural mineral, which makes it an excellent abrasive. To obtain polished diamonds, they can only be processed under high pressure and high temperature with other diamonds (known as Type-II diamonds) that are harder, or with substances that are harder than diamond itself. These substances can be borazone, ultra-hard fullerite, or diamond nanorods. This also means that the diamond retains its surface polish — its excellent shine. Diamond has a melting point of 3547 °C — the highest of any mineral.
