Lab diamonds are created in a controlled environment using cutting edge technology and have identical chemical, physical and optical properties of mined diamonds that come from the earth. Grown diamonds start as a carbon seed, and as heat and pressure are applied through Chemical Vapor Deposition (CVD) or High-Pressure High-Temperature (HPHT) growing methods, the seed grows to form pieces of carbon that are then cut and polished into gems. Thanks to science, lab grown diamonds are an ethical and more attainable option for your fine jewelry. PLAY VIDEO Made, not mined.
