# CVD

Also called chemical vapor deposition, CVD diamond

CVD, chemical vapor deposition, is one of the two usual methods for growing diamond in a laboratory. The other is HPHT.

## In more detail

A CVD-grown diamond is diamond, with essentially the same properties as a natural one. Only a gem lab's instruments can tell the two apart.

## On a grading report

GIA's Laboratory-Grown Diamond Report (2020 to 2025) stated CVD or HPHT. IGI can note CVD as the growth method in Comments on request.

## Related terms

- [HPHT](https://digitalgemology.com/learn/glossary/hpht): HPHT stands for high pressure, high temperature. The same conditions can grow a diamond in a laboratory or treat a natural one to change its color.
- [Laboratory-grown diamond](https://digitalgemology.com/learn/glossary/laboratory-grown-diamond): A laboratory-grown diamond is a diamond that people grow with machines, by HPHT or CVD. It has essentially the same composition, crystal structure and properties as a natural diamond.
- [Laboratory-Grown Diamond Report](https://digitalgemology.com/learn/glossary/laboratory-grown-diamond-report): The Laboratory-Grown Diamond Report was GIA's digital-only report for laboratory-grown diamonds, from October 2020 to September 2025. It gave color and clarity grades and stated the growth method, CVD or HPHT.
