Our lab diamonds are graded with the same strict standards as natural diamonds – by using the 4C’s: Cut, Color, Clarity and Carat Weight. Lab grown diamonds are sold with diamond grading reports that certify their quality and provide traceability.

All Promise by Effy lab created diamonds are made with the CVD process. A narrow slice of diamond seed is placed in a sealed chamber. The chamber is filled with hydrocarbon gas mixtures and the seed is ionized. This causes the molecular bonds in the gases to break down so the pure carbon sticks to the diamond seed. Once the lab-grown diamonds are fully formed, they’re expertly cut and crafted to unleash their maximum fire and scintillation.
