Lab-Grown Diamonds
100% optically, chemically, and physically identical to natural Diamonds
Lab-grown Diamonds are not simulants. Scientists create them in a lab. They start with rough crystals, and use HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) — sometimes both methods. Lab-grown Diamonds can cost 30-50% less than natural Diamonds.

Diamond Screening and Testing at Stuller
Stuller does not tolerate undisclosed lab-grown Diamonds in our inventory. As added security, we further require our suppliers to screen for undisclosed lab-grown Diamonds before using any Diamonds in our products. Random samples of Diamonds from all of our suppliers are also periodically sent out to leading laboratories to check for lab-grown Diamonds. By incorporating these protocols, Stuller extends confidence and security to our customers, ensuring that you are getting exactly what you purchase.
