HRD ANTWERP NOW GRADES SYNTHETIC DIAMONDS
HRD Antwerp has begun to issue gemological certificates for lab-grown diamonds. According to the Antwerp-based lab, every synthetic diamond tested will be issued its own, green colored certificate, which is different in color than the certificates issued for natural diamonds at the lab.
The lab promises that every synthetic diamond’s girdle will be laser inscribed with the words “Lab Grown” along with the number of the grading report. On the identically-numbered report, it will be mentioned that the diamond was laser inscribed.
Every synthetic diamond graded by HRD is tested by the same criteria as natural diamonds. Certificates for synthetics will also detail every stone 4Cs – Color, Clarity, Cut and Carat Weight.
