What is CVD?

CVD stands for chemical vapor deposition. CVD diamonds are grown in labs. CVD diamonds rely on a special process called Chemical Vapor Deposition This process begins with a diamond seed crystal (often produced through HPHT) placed in a sealed chamber. . A carbon-rich gas, such as methane and hydrogen, is then pumped into the chamber along with other gases. The gasses are then ionized into plasma using a technology similar to lasers or microwaves, which breaks down the molecular bonds in the gases and cause carbon atoms that accumulate on the crystal and form a diamond. In addition to natural gas, the crystal is treated with high temperatures and pressures within the chamber to remove any coloration and make the diamond colorless.
