Ultra High Pressure Diamond Press

Natural diamonds are produced over 120 to 130 km deep inside the earth in an extreme environment of 1,500°C and 4.93GPa (50, 000 atmospheric pressure). However, we cannot get them until magmas bring them up above ground. Ultrahigh Pressure Diamond Press can provide these processes artificially in a short time.
