Natural diamonds are formed under high pressures and temperatures deep within the Earth's mantle. However, scientists have been able to replicate this process artificially using high-pressure, high-temperature methods since 1955. Recently, researchers have developed a new method to grow diamond crystals at much milder conditions—1 atmosphere of pressure and 1025°C—using a liquid metal technique, which could revolutionize diamond synthesis.
