As of 2018, the Federal Trade Commission (FTC) considers both lab-grown and mined diamonds to be real. The only difference between the two is their point of origin. Unlike a mined diamond, a lab-grown diamond such as a DIAMIND diamond has guaranteed origin.
The naked eye cannot tell the difference between a lab-grown and mined diamond. Most trained gemologists cannot tell the difference between a polished mined diamond and a polished lab-grown diamond without using advanced technology— traditional methods and machinery cannot tell the two apart.
