As of 2018, the Federal Trade Commission (FTC) considers both lab-grown and mined diamonds to be true diamonds. The only difference between the two is the point of origin and its impact on the environment.

The naked eye cannot tell the difference between a lab-grown and mined diamond. Most trained gemologists cannot distinguish between a polished mined diamond and a lab-grown diamond without using advanced technology—traditional methods and machinery cannot differentiate between the two.
