Earth-mined and man-made diamonds are almost indistinguishable, and are made of pure carbon. The difference lies in the scientific process in which they are created.
Natural diamonds are formed beneath the earth’s crust resulting from extreme pressure over millions of years.
Lab created diamonds start with a small diamond seed placed in a sophisticated pressure chamber containing carbon. By recreating the intense heat and pressure of the earth’s crust, the diamond grows layer by layer. Approximately 10 to 12 weeks later a diamond is formed.
