CVD stands for Chemical Vapor Deposition, and it is a process used to create lab-grown diamonds. In this process, a diamond seed crystal is placed in a vacuum chamber, which is then filled with carbon-rich gases and heated to nearly 1500 degrees Fahrenheit. The gas turns into plasma from these extremely high temperatures, causing the release of carbon pieces. These carbon pieces become layered onto the diamond seed, which grows the diamond. CVD diamonds are identical to natural diamonds in terms of their physical properties and chemical composition. They are also graded for cut, color, clarity, and carat weight just like natural diamonds. CVD diamonds are often called synthetic diamonds or CVD synthetics, but they are 100% authentic diamonds. It is impossible to tell a CVD diamond apart from a natural diamond without specialist equipment. CVD diamonds are less expensive than natural diamonds and are more environmentally friendly since they dont come from mines and are not used to fund conflict.
