Lab-grown diamonds are manufactured using one of two processes, high pressure and high temperature (HPHT) or chemical vapor deposition (CVD). HPHT mimics the Earth's natural process of creating diamonds, using extremely high heat and pressure conditions of about 2000°C and over 1.5 million PSI. Diamonds made using CVD are a newer development.

The HPHT Diamond Growth Process Diamond seed is placed in a specifically designed press. The growth chamber is heated to 1300-1600 °C with pressures above 870,000 pounds per square inch. The molten metal dissolves the high purity carbon source. Carbon atoms precipitate on a small diamond seed crystal, and a synthetic diamond begins to grow.

HPHT (high-pressure high-temperature) is the traditional method of making synthetic diamonds. The lab-created diamond is grown within a small capsule located inside a mechanism (a press) capable of generating extremely high pressures. The man-made diamond is formed from a molten metal alloy, such as Iron, Nickel or Cobalt.
