First thing first, lab-created diamonds are REAL diamonds. As the name implies, these diamonds are grown in a highly-controlled laboratory that recreates conditions of the Earth’s natural environment. Lab-created diamonds are chemically, physically, and optically the same as earth-mined diamonds. The only difference is the point of origin as one is extracted from the ground while another is grown above ground.
Lab-grown diamonds share the same physical and atomic properties as natural diamonds, and are indistinguishable from natural diamonds when viewing with the naked eye. These man-made diamonds can be tested with specialised equipment in a gemological laboratory.
