Natural diamonds are created over a period of three billion years at least 85 miles below the earth’s mantle under the natural condition of very high pressure and high temperature. Once a diamond has been created in these underground conditions, it travels via molten rock to the earth’s surface, where it is mined, refined and turned into used for industrial purposes or beautiful jewellery.
