Scientists have developed a novel method to create lab-grown diamonds without the extreme pressure typically required. This technique, reported in the journal Nature, involves exposing a liquid of gallium, iron, nickel, and silicon to a carbon-rich methane gas at 1025° Celsius. The addition of silicon initiates the growth process, allowing diamond crystals to form without the need for a diamond seed. This breakthrough could simplify the production of diamonds for industrial and scientific applications.
