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 are grown using either 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.
