Synthetic diamonds are sometimes referred to as laboratory-created diamonds, laboratory-grown diamonds, or cultured diamonds, and are manufactured diamond crystals produced by man, not nature.

Synthetic diamond can be optically and chemically identical to natural diamond.
Gem-quality synthetic diamonds are predominantly cubic and octahedral in the rough form. Impurities are common, but as the technology has progressed so the rough diamond crystals have improved. A diamond's hardness can vary depending on its impurities and crystalline structure.

DCLA does not certify synthetic diamonds, but laboratories that do opt to certify synthetic diamonds must clearly state on the certificate that the diamond is a laboratory-created, synthetic diamond.
