Lab grown diamonds (also called lab created, man made, engineered, synthetic or cultured diamonds) are chemically, optically and physically identical to earth mined diamonds, but are more ethical, beautiful and affordable than any diamond we will ever get out of the earth. We're replicating the earth's natural process by crystallizing carbon in ...
2004-2-25 · This photograph shows a synthetic brilliant cut single-crystal diamond grown by chemical vapor deposition, CVD. About 2.5 mm high, this crystal was grown in about 1 day at Carnegie. The very bottom (table) of the crystal is a type 1b seed: hence the yellow tint which is due to internal reflection (the CVD diamond is transparent).
