Lab-grown diamonds are produced using High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD) methods. HPHT simulates the natural diamond formation process by applying high pressure and high temperature to a carbon source. In contrast, CVD involves breaking down carbon-rich gases in a vacuum chamber to deposit carbon atoms onto a diamond seed. Both methods result in diamonds that are physically, chemically, and optically identical to natural diamonds. This production process is faster and more environmentally friendly, reducing the need for extensive mining operations.
