What Exactly is a Diamond?
A symbol of wealth, purity and love, a diamond leaves no one unmoved. In mineralogy, diamond is an extremely hard, highly refractive crystalline form of carbon that is usually colorless and can be usedin abrasives, and other applications. Diamond is carbon in its most concentrated form, often occurring as octahedrons with rounded edges and curved surfaces. Diamonds are formed at incredible depths of the earth, between 150 and 300 km below the surface and under conditions of extreme temperature and pressure. They are most commonly found in volcanic breccias and in alluvial deposits, pushed up by a kind of volcanic eruption through volcanic pipes of diamond bearing rock such as kimberlite. With gradual erosion, kimberlite chimneys were exposed at the earth’s surface.
