Lab grown diamonds from Labcreateddiamond store are of two gem-quality diamond creation processes: High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). In both processes, a small diamond seed is placed in an environment that contains carbon, the atomic component of a diamond. Under suitably controlled conditions, the diamond grows, atom-by-atom, layer-by-layer, recreating nature's process. These diamonds are then cut & polished in our factories by qualified artisans to give the rough diamond great brilliance with excellent to ideal cut, symmetry and polish parameters.
