Grading Certificates & Laboratories

What a certificate proves, labs you may encounter, and how verification links combat substitution.

A laboratory certificate is geometry + inclusion mapping + nomenclature—never a resale guarantee. Its job online is aligning expectations before money moves.

What PDPs surface here

  • Laboratory acronym + alphanumeric report number clickable to verifier portals.
  • Optional grading scan JPG / TIFF + PDF appendix when suppliers provide files.
  • Kimberley / conflict-aware narrative for naturals.

Why lab lookup matters

Substitution fraud is overwhelmingly about mismatched certs. Always cross-check inscription numbers with video of the inscribed girdle. Our storefront stores explicit verification deeplinks so you aren’t chasing PDFs.
