How are lab-grown diamonds made?


There are a few methods used to grow lab-grown diamonds. Typically, lab-grown diamonds start with a tiny lab grown diamond, like a seed. The seeds are placed in a chamber called a plasma reactor (in the case of CVD synthesis) or a large mechanical press (if manufactured by HPHT). Then, depending on the technology used, some combination of heat, pressure and a carbon source are used to make the crystals grow, layer by layer.
