Diamond Education: How are Lab-Grown Diamonds Created? Learn the differences between CVD, HPHT, and their respective growing processes — Lab-Grown Diamond

100% optically, chemically, and physically identical to mined 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 mined Diamonds.              Chemical Vapor Deposition (CVD) The CVD process was invented first— in 1952 by William Eversole at Union Carbide. This process allows diamonds to grow in an entirely different way than the HPHT process. CVD starts with a natural diamond slice (or seed) placed in...
