Frequently asked

How do I verify a JTR report?

Go to Report Search and enter the report number printed on your certificate or engraved on the girdle. You’ll see the full grading record and a confirmation that the report is authentic.

My REVEAL device won’t power on — what should I do?

Ensure the unit is charged for at least 30 minutes with the supplied adapter. If it still won’t start, hold the power button for 10 seconds to reset, then contact support with your serial number.

How often should instruments be calibrated?

We recommend a calibration check every six months, or after any significant transport. The REVEAL software will prompt you when a calibration is due.

Can I get a replacement report?

Yes. As long as the stone carries its laser inscription and matches our database, we can reissue a report. Start a request through Contact.

Still need a hand?

Our support team responds within one business day.
