How we verify

Every supplier, checked in person.

The gem trade runs on trust — and trust doesn't scale through web forms. A GemSurf verification means a real person met the supplier and reviewed their business. No badge without a visit.

1

Application

The supplier submits business details, trade licenses and any gemological certifications.

2

In-person check

A GemSurf team member visits the supplier on-site and reviews the business against what was submitted.

3

Listed

If everything checks out, the supplier is approved and appears in the directory with the Verified mark.
