True Origin™ Collection Lab-Grown diamonds are man-made diamonds that are chemically, physically, and optically identical to diamonds originating from nature. Both have the same chemical composition and atomic structure, producing the very same durability, fire, and sparkle. Laboratory grown diamonds are a testament to the use of technology and human achievement. “Lab-Grown” most accurately describes the man-made diamond production process in which the crystal structure is grown from the seed diamond. Lab grown diamonds are the result of an extemporaneous crystallization process rather than a synthesis of compounds.
Lab-Grown diamonds utilize a Chemical Vapor Deposition (CVD) process or a High Pressure High Temperature (HPHT) method that cause carbon atoms to crystallize into the structure that renders them harder than any other form of carbon and harder than any other material. Both processes require advanced technological equipment and both produce rough diamonds that are then cleaned, cut, and polished in the very same way that naturally-occurring, mined diamond rough is processed.
Diamond growth can be initiated only when a pre-existing diamond seed or a sliver of diamond substrate is present for the carbon atoms to attach to and “learn” the diamond’s strong tetrahedral crystal lattice. The “seed” essentially serves as a blue print for the crystallization process as carbon atoms stack one-by-one on the carefully selected seed.
Lab-Grown diamonds are graded to the same carat, clarity, color, and cut specifications as mined diamonds and they can be accompanied by the same type of Diamond Grading Reports written by leading independent gemological institutes and certified appraisers.
