What Is A CVD Diamond?

CVD refers to Chemical Vapor Deposition. It's the process in which natural gases such as methane breakdown into carbon atoms and gathers around a starter diamond to create a new diamond. According to the Gem Society, CVD diamonds are artificial diamonds grown in the lab. These diamonds do not differ from natural or mined diamond since they are made from the same materials and under similar conditions.

How Are CVD Diamonds Made in the Lab?

The process starts with placing a "seed" diamond in a sealed chamber where it's exposed to high temperatures of around 800°C. Introducing a gas mixture rich in carbon, mainly methane or hydrogen, into the chamber follows. These gases break down, releasing pure carbon atoms that attach to the surface of the seed diamond. Atomic bonds form between the seed diamond and carbon atoms to create a new larger diamond. The process results in a layer-by-layer formation of a gorgeous, genuine diamond.

History of CVD Diamonds

General Electric (GE)/DeBeers was the first company to create diamonds in the lab in 1955. During this time, GE/DeBeers was using the HPHT method. This technological innovation set the stage for developing the CVD method in the 1980s, making CVD diamonds a reality. Since then, these diamonds have been increasing in popularity.

Pros of CVD Diamonds

  • Environmentally friendly
  • 100% carbon, thus high-quality diamonds with fewer impurities
  • Available in many colors
  • Ethically created because they are not used to fund conflicts
  • Cheaper than natural diamonds

Cons

  • Lack of the highly respected certification that comes with natural diamonds
  • Almost impossible to differentiate them from mined diamonds
