HRD, a subsidiary of the Antwerp World Diamond Centre (AWDC), says it is the first lab to stop lab-grown certification, although it will still issue certificates for jewelry containing lab-grown diamonds.
The move, announced on 18 June follows GIA’s decision earlier this month to grade lab-grown diamonds only as premium or standard, without scores for color or clarity.
HRD started grading lab-grown diamonds in 2013, albeit with fewer grades of color and clarity than natural diamonds. In 2019 it aligned lab-grown diamonds with natural stones, a move that appeared to signal greater parity between the two sectors.
