Chemical Vapour Deposition
In the CVD process, a tiny “seed” diamond is placed in a sealed chamber and heated to a high temperature. The chamber is filled with carbon-rich gases like methane. These gases are ionised into plasma, breaking molecular bonds and allowing carbon atoms to crystallise on the seed diamond, building it layer by layer. The result is a beautiful, high-quality diamond created in a fraction of the time it takes for natural diamonds to form.
