What is Lab created diamonds?
Lab created diamonds are grown in highly-controlled laboratory conditions that simulate the earth’s natural growing environment, producing real diamonds that are optically, physically and chemically identical to earth mined diamonds.

High Pressure High Temperature (HPHT) is our primary growing process, while Chemical Vapor Deposition (CVD) is commonly used to produce diamonds for industrial purposes.
