Diamond, also called a gemstone, is a gemstone formed by pure carbon atoms in crystallizing conditions. It can be found all over the Earth's surface and has high market value and is considered one of the most valuable gems. To be commercialized, the stone must go through a process that includes stoning and evaluation of its characteristics. Diamond is the most valued gemstone in the gemstone trade and is used to make luxury jewelry. Because they are very resistant stones, they are also used in the industrial sector for excavation activities. Diamonds (natural and synthetic) are used as drills, mainly in the excavation of gas and oil wells.
