Natural Diamonds
Natural diamonds are formed deep within the Earth's mantle under conditions of high pressure and high temperature. The process takes place at depths of around 140 to 190 kilometers below the Earth's surface. These conditions cause carbon atoms to bond together, forming the crystal lattice structure that we recognize as a diamond.
The Earth's mantle is primarily composed of solid rock, which includes minerals such as olivine, pyroxene, and garnet. Diamonds can be found within these mantle rocks, often as inclusions in minerals like garnet and pyroxene. The presence of these minerals in diamonds provides valuable information about the formation and origin of natural diamonds.
