Diamonds, the hardest of all minerals, are not only used in the jewelry industry, but are present in many technologies which need resistant smooth-cutting tools. Diamonds form at a depth greater than 150 kilometres within the earth in distinctive parent rocks called kimberlites. Kimberlites also include several characteristic minerals that are very important as indicators in diamond exploration activities.
