What Is A CVD diamond?

A CVD diamond is a lab-grown diamond. They are created entirely differently from traditional diamond production and produce a "synthetic," or laboratory-created, diamond. With more than 50 years of making lab-created diamonds, CVD diamonds are some of the most advanced and best-looking copies on the market today.

CVD diamonds are used for many things, including jewelry and industrial applications like semiconductors.

How are CVD diamonds made?

CVD diamonds are made by carbon vapor deposition, which involves the application of heat to a diamond seed. Carbon atoms are then deposited on the source, heated to high temperatures, and removed from the diamond to create one. The process can take several months or years, depending on how much time is needed for each step.

CVD diamond properties

CVD diamonds have the same chemical composition as mined diamonds: carbon and hydrogen atoms bonded through carbon bonding (hence "CVD"). The bonds between these components create a very high melting point for your gemstone: 685 degrees Celsius (1,470 degrees Fahrenheit). The bonds mean you can heat your CVD diamond or set it in jewelry without fear of damaging it to either party involved!

Synthetic CVD diamonds vs. naturally mined diamonds

The difference between naturally mined diamonds and synthetic CVD diamonds is:

  • Natural mined diamonds are made by nature. They're mined from the Earth and cut into shapes that suit their owner.
  • Synthetic CVD diamonds are artificial. They can be created from many different sources, but they have one thing in common—they're all made up of carbon atoms with extra hydrogen atoms attached. The carbon atoms mean they have a lower melting point than real gems do because there isn't as much carbon there to keep their shape intact.

Significant benefits of a synthetic CVD diamond

The significant benefits of synthetic CVD diamonds are; they are less expensive than mined diamonds and more eco-friendly as they don't need to be dug up from the Earth. They're also incredibly hard, which makes them ideal for jewelry use—they can withstand all kinds of wear without losing their shine or luster over time.


CVD diamonds are lab-grown diamonds. CVD diamonds are an excellent choice because they are durable and beautiful diamonds at an affordable price. CVD diamonds also have a unique, attractive coloration. If you have any questions or want to learn more about CVD diamonds, please contact Greis Jewelers.
