Lab-created diamonds are produced by utilizing 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 diamond. Under suitably controlled conditions, the diamond grows, atom-by-atom, layer-by-layer, recreating natures process. How do lab-created diamonds and natural diamonds compare? Both have the same physical, chemical and optical properties and emerge as rough diamonds.
Both have the same hardness, specific gravity, refractive index and dispersion factor; are polished using the same equipment and techniques; and have the same brilliance, sparkle, fire and scintillation. Both are, in fact, diamond.
