CVD Diamond Stone
A CVD diamond is a diamond created by a process called Chemical Vapor Deposition. This process begins with a diamond seed crystal, typically from a high-quality synthetic diamond, in a vacuum chamber. Natural gas, such as methane, is then pumped into the chamber and broken down into 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.
