AI Overview
Man-made (lab-grown) diamonds are identical to natural, earth-mined diamonds in their chemical, physical, and optical properties, but differ in their creation process, origin, cost, and value. Natural diamonds form over billions of years deep within the Earth's mantle, while lab-grown diamonds are created in a laboratory within weeks by scientifically replicating these conditions. While both are "real" diamonds, natural diamonds are rarer and hold greater long-term value and investment potential, whereas lab-grown diamonds offer an alternative at a lower cost.
