DPP in jewellery: provenance, authenticity and verified resale

Jewellery is probably the use case where the Digital Product Passport shines most. High value, provenance that matters, authenticity that commands a premium and a huge second-hand market: exactly the problems a DPP solves best. This guide explains why, and shows what it looks like in practice.

Why jewellery is an ideal case

Four traits make jewellery the perfect ground for a DPP:

• High value per item — it justifies the effort of tracing each unit, not just the model.
• Sensitive provenance — origin of metals and gems, responsible mining, chain of custody.
• Authenticity — counterfeiting destroys value; a verifiable passport protects it.
• Active resale — second-hand takes off when the buyer can trust the history.

What the DPP solves in jewellery

A passport per piece turns problems into advantages:

• Anti-counterfeiting: a unique, verifiable identity on every piece.
• Trusted second-hand: resale with provable provenance and condition — more resale value, less fraud.
• Re-certification with lineage: repair, refurbish and re-certify without losing the history.
• Future compliance: early readiness for traceability and sustainability requirements.

From theory to practice: an operating case

This is not a hypothetical proposal. Today there is an operating jewellery demonstrator that issues Digital Product Passports for more than 3,000 pieces, with GS1 EPCIS 2.0 documents and an exportable, self-describing passport for each piece. It is a real and bounded case —a demonstrator, not a mass deployment with multiple clients— and precisely for that reason it lets us show the how with real data instead of promises.

What standards it is built on

Identity is assigned with GS1 identifiers and lifecycle events are recorded with GS1 EPCIS 2.0. The result is a portable passport, readable by third parties and aligned with the ESPR and the Data Act — not a certificate trapped in a closed PDF.

From the authenticity certificate to the living passport

Jewellery has used paper certificates for decades. The DPP turns them into something alive: instead of a static document that gets lost, a record that travels with the piece across owners, accumulates its history (sale, repair, resale) and can be verified in seconds. It is the thesis of our research: the value is not in the label but in the governed data that supports it.

Frequently asked questions

Does it work for small jewellery workshops?

Yes. In fact the high value per piece makes it worthwhile to trace even small production runs. You start with one collection and grow in phases.

Does the buyer need a special app?

No. A QR code or NFC on the piece opens the passport; the consumer sees what is relevant and the systems read the rest.

Does this replace my authenticity certificate?

It enhances it. The DPP can incorporate the certificate’s information and make it verifiable and portable, instead of relying on a paper that gets misplaced.
