Exporting gems and jewellery β€” Kimberley, hallmarking and provenance

Last reviewed 2026-10 Β· 4 sections

Gems and jewellery move at very high value per kilogram, which makes documentation and provenance the whole game. Much of the compliance is not customs at all β€” it is about where the stones came from.

Classification runs across chapter 71

  • 7102 β€” diamonds, split between rough and worked, and whether industrial or non-industrial. Rough versus polished is a different line, not a description.
  • 7103–7104 β€” other precious and semi-precious stones, natural and synthetic.
  • 7113 β€” articles of jewellery of precious metal. A piece of jewellery is classified as jewellery, not by the stones set in it; the stones do not drive the heading.

Rough diamonds: the Kimberley Process certificate

Rough diamond shipments must travel under the Kimberley Process Certification Scheme: a government-issued certificate accompanies each shipment, and the goods must be sealed and an unbroken chain of certificates maintained from producer to import. This is a hard legal requirement in participating countries, not a voluntary scheme.

The failure mode is administrative: a shipment that lacks the certificate for a leg of its journey cannot legally move. Maintain the certificate chain as a physical artefact β€” a scanned file is not the certificate.

Provenance now goes beyond Kimberley

  • Sanctions-based measures on certain origin diamonds have been introduced in some markets and are evolving. A stone that is legal to trade may still have to demonstrate that it is not of a prohibited origin, with documentary evidence of the supply chain.
  • Responsible-sourcing frameworks required by major buyers are commercial requirements β€” they do not replace the legal certificate, and the legal certificate does not satisfy the buyer's framework. Evidence both, separately.
  • Keep stone-level records: parcel identity, invoice trail, and any warranty about origin or treatment (for example, treatment disclosure for coloured stones).

Indian requirements and documents

  • Hallmarking of gold jewellery under the national standards regime applies in the domestic market and to buyers who require it; check the current rules for the specific product and destination.
  • Documents: commercial invoice with full stone and metal description, packing list, transport document, certificate of origin, Kimberley certificate for rough diamonds, and any buyer-scheme or sanctions documentation.
  • Insurance and secure logistics are part of the cost structure β€” value density changes the economics of freight in a way that general cost guides do not capture.
