Can I check a report while I'm here?
Yes. Enter the report number on the lab's own website, then match the laser inscription on the girdle to the report under 10x magnification. An online lookup shows the report is genuine; only the girdle inscription shows the stone in front of you is the one in the report. See verify a certificate.
