Optically, chemically, and physically identical, Just 1 to 3 Billions Years Younger
A laboratory-grown diamond is a man-made product that shares the chemical and optical properties of natural diamonds, but whose origin differs greatly. Lab-grown diamonds are produced in factories in approximately 2-3 weeks. They start with rough crystals and are grown using either HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition).
While they may look similar to the untrained eye, lab-grown diamonds are not identical to natural diamonds and can be distinguished with the proper tool. It’s a common myth that they are identical, but the rapid manufacturing process of lab-created diamonds always leaves telltale marks within the stone that can be identified by experts with 100% certainty.
