The diamond seed is positioned in a chamber, which is then exposed to temperatures of close to 1500 levels Celsius and pressures of all over 60,000 atmospheres. The conditions mimic people located deep in the Earth, where normal diamonds are formed. Over a period of time of months or months, the HPHT diamond grows larger as extra pure carbon is extra.
