Diamonds are formed as an allotrope of the element carbon, at depths greater than 90 miles. The pressure and heat at this depth is critical to the formation of the diamonds thâ¦at are mined at the surface today. At crustal pressures, the stable form of carbon is the allotrope graphite.
Diamond Clarity. The formation of a diamond is not a gentle process. Most diamonds are born in extreme circumstances from primeval carbon deep in the earthâs mantle at about 500,000 to 2 million feet below the surface. They are then shot up to the surface at supersonic speeds by eruptions inside the earth.
