To successfully grow diamonds scientists need to recreate the conditions where diamonds grow deep below the earth’s surface. They scientifically replicate an environment of extremely high pressure and high temperature.
The exact same process that a natural diamond undergoes underground through nature is reproduced in the laboratory. A rough lab grown diamond is grown from a small diamond seed. The diamond seed is placed in an environment that contains carbon, the molecular component of diamonds. After applying tremendous pressure and very high temperatures, under highly controlled conditions, the small diamond seed begins to grow, molecule by molecule, layer by layer, emulating nature’s process. The result is a rough diamond which can be cut and polished for use in jewelry like any other naturally mined diamond.
