How Are Lab Grown Diamonds Created in the Laboratory?

Lab-grown diamonds, also known as synthetic diamonds, are created through highly controlled technological processes in laboratories. These diamonds have the same physical, chemical, and optical properties as natural diamonds. The creation process involves two main methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). We will explain the detailed process of creating such diamonds from this article.

Production of Lab Grown Diamonds

There are two methods used in the production of lab grown diamonds, HPHT and CVD. Only after producing diamonds through these processes, they are used in making jewelry like Necklaces, rings, bracelets, etc.

HPHT Method

The HPHT method mimics the natural conditions under which diamonds are formed deep within the Earth. This process involves three primary components: a carbon source, a small diamond seed, and a metal catalyst.

Chemical Vapor Deposition (CVD) Method

The CVD method involves growing diamonds from a gas mixture. This technique allows for the production of high-quality diamonds at relatively lower temperatures and pressures compared to HPHT.


These are the two methods used in the production of lab grown diamonds. These diamonds are very similar in quality when compared to natural diamonds and also they are highly affordable than the latter.
