Trust & Verification
A color grade is only as trustworthy as the person and method behind it. GemMetric™ earns that trust with transparent science and a verified expert community.
Expert verification program
Industry professionals can apply for verified status by submitting a recognized credential. Verified experts gain access to expert-tier tools — including the ability to submit confirmed entries to the Gemstone Vault and provide feedback that strengthens the reference database.
Submit your GIA G.G. number for directory verification. Approved gemologists earn expert-tier access, including the ability to submit verified entries to the reference vault.
AGS members can verify via their member ID. The same expert-tier privileges apply once approved.
No directory-listable credential? You can still apply using a public LinkedIn profile that demonstrates professional gemological experience.
What a GemMetric™ report looks like
Every grade produces a traceable report — serial-linked, confidence-scored, and tagged with the evidence tier of its matched reference. Here’s an illustrative example:
