Verification
Verify the record.
Every Gem Passport can be reduced to a cryptographic digest of its documented facts — identity, weight, colour, clarity, cut, origin assessment, treatment status, certification references and provenance sequence. Enter a Gem ID and we recompute that digest in your browser, then compare it with the digest recorded in our verification ledger.
How verification works
- The documented facts of the gemstone are serialised in a fixed, key-sorted order so the same record always produces the same text.
- That text is hashed with SHA-256 in your own browser.
- The resulting digest is compared with the digest we recorded when the passport was issued. Where a record has been anchored to an external ledger, the reference is shown alongside it.
Verification confirms that recorded documentation has not been altered. It is not a valuation, an authentication of the physical stone, or a guarantee of future value. Independent laboratory certification remains the authority on gemmological identity.
