Diamond growth techniques refer to methods used to create synthetic diamonds in a laboratory setting. The two primary techniques are High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). HPHT mimics the natural conditions under which diamonds form in the Earth, using high pressure and temperature to crystallize carbon. In contrast, CVD involves breaking down carbon-containing gases to deposit carbon atoms onto a substrate, allowing them to crystallize into diamond. Both methods produce diamonds that can be used in various applications, including jewelry and industrial tools, while also offering a more sustainable alternative to mined diamonds.
