This analysis is an AI-generated visual approximation based on photograph(s). Per-attribute confidence scores reflect what can realistically be assessed from images alone. It is not a certified gemological appraisal and should not be used for valuation, insurance, or sale without professional verification.

How it works

Three steps.

  1. 01

    Sign up

    Create an account with email or Google. GRADIX uses your own login — not a team.

  2. 02

    Upload and analyse

    Add 1–5 photos. GRADIX returns a field-by-field visual estimate with confidence scores.

  3. 03

    See past analyses

    Every analysis stays in your history so you can open it again later.

What you get

A structured first look

  • Shape
  • Carat range
  • Colour estimate
  • Clarity range
  • Cut / optics
  • Notes

Not a laboratory report

GRADIX is a supplementary visual approximation. It does not replace a PAGI or HRD Antwerp gemologist, and must not be used for valuation, insurance, or sale without professional verification.
