Diamond Seed Preparation:

a. The diamond seed is carefully cleaned and optionally attached to a substrate inside the boom chamber

Creating a High-Pressure Environment (HPHT):

a. The HPHT chamber is sealed, and the surroundings is evacuated to eliminate impurities and gases.

B. Carbon, in the form of high-purity graphite, is placed in contact with the diamond seed.

C. Pressure within the chamber is raised to numerous gigapascals (GPa), usually round five-7 GPa.

Creating High Temperature (HPHT):

a. Electrical resistance heating or laser beams are used to raise the temperature to around 1,four hundred-1,six hundred levels Celsius.

B. This high temperature allows carbon atoms from the graphite to dissolve into the diamond seed and shape new carbon lattice structures.

Creating a Controlled Environment (CVD):

a. The CVD chamber is sealed, and the surroundings is evacuated to get rid of impurities and gases.

B. A combination of high-purity methane (CH4) and hydrogen (H2) is brought into the chamber, developing a controlled surroundings.

C. Microwave plasma or warm filament activation raises the temperature to around seven-hundred-900 stages Celsius.

Growth and Monitoring:

a. In HPHT, carbon atoms dissolve into the diamond seed and progressively form a bigger diamond crystal over the years.

B. In CVD, carbon atoms from the methane gasoline deposit onto the diamond seed's floor, creating new layers of carbon and developing the diamond.

C. Growth time can vary from several days to several weeks.

Cooling and Depressurization:

a. In HPHT, the chamber is slowly cooled and depressurized to reduce temperature and pressure.

B. In CVD, the gasoline flow is regularly reduced, and the chamber is cooled to return to everyday conditions.

Harvesting and Cutting:

a. The grown diamond is harvested from the substrate or graphite.

B. It is then cut and polished into the desired shape and length.

Quality Control:

a. The lab-grown diamond undergoes rigorous quality checking out and evaluation to ensure it meets the favored characteristics and requirements, which include the "Four Cs" (carat, reduce, clarity, and colour).
