ABOUT LAB-GROWN DIAMONDS Lab-grown diamonds are real diamonds — not simulants. Instead of forming over millions of years in the earth’s mantle, they are created in rough crystal form by scientists. They are optically, visually, and chemically identical to natural diamonds. THE BENEFITS OF LAB-GROWN DIAMONDS The diamonds arrive with: - A certificate from GCAL (Gem Certification and Assurance Lab) or IGI (International Gemological Institute)
- A unique inscription on the girdle
HOW THE LAB-GROWN DIAMONDS ARE MADE Our lab-grown diamonds are grown from the tiny carbon seeds of pre-existing diamonds. There are two primary methods used to create diamonds in a laboratory: CVD (Chemical Vapor Deposition) and HPHT (High-Pressure High Temperature). Our product involves a combination of both. The HPHT method involves the application of high temperatures and pressures to a small seed crystal, while the CVD process “grows” the diamonds from the chemical reaction of distilled carbon gas and a seed crystal. Our lab-grown diamonds are created using the CVD method and are further treated using HTHP to improve the color. LAB-GROWN DIAMOND JEWELRY Our lab-created diamond jewelry offers excellent value and is slightly more affordable than natural diamonds of comparable size and quality.
