Lab-grown diamonds are made in a lab, Chemical Vapor Deposition (CVD). The process starts with what is known as a “diamond seed,” a single crystal diamond in a slice about as thick as a human hair is placed into a chamber. This is then exposed to a carbon-rich gas and fired-up up to extremely high temperatures. Over a matter of just weeks, the carbon gas converts and the particles stick to the original diamond slice, before eventually crystallising into a fully formed diamond.

In the same way as natural diamonds, lab-grown diamonds go through strict grading assessment during certification by grading laboratories like GIA. They assess the lab-grown diamond by the usual cut, colour, and clarity standards amongst other details. Therefore, you can find a lab-grown diamond equally beautiful as a top-quality natural diamond and certify that the diamond is lab created by CVD.
