Provenance Claims

This page is designed to answer your questions on the requirements of provision 12 named ‘Provenance Claims’ of the Code of Practices (COP).

This provision allows members that make claims about the provenance of materials (source, origin or practices used when sourcing), to have these audited as part of their RJC COP audit. It does not require members to make provenance claims so it is only audited if it is applicable to your company, and you want to make a claim.

If you have any further questions on the provenance claim provision, please email our dedicated Training Manager, Maria Mursell on

Let’s look at some example claims:

Clear acceptable claimsNot acceptable claims

When provenance claims are certified by the RJC through an audit, these appear on your certificate. To encourage transparency as to what you (the member) does to verify the claim it is best practice to include reference to the criteria and/or systems you are using within the wording of the claim itself. This means external stakeholders will understand better what it is you do to make sure you source in accordance to your claim.

Here are some examples to explain, with the system and/or criteria behind the claim in green:

  1. “We source conflict-free gold in accordance with the Signet Responsible Sourcing Protocol.

  2. Based on written assurance from our suppliers, our diamonds have not originated from the Mbada and Marange regions of Zimbabwe”.

  3. “We source all our gold responsibly from only LBMA Good delivery list refiners.

  4. “We source conflict-free gold in accordance with the OECD Due Diligence Guidance for Responsible Supply Chains for Minerals from Conflict-Affected and High-Risk Areas.

  5. “All our diamonds are natural, all having been checked in a synthetic diamond testing machine to ensure this.”

  6. “All our diamonds are sourced from Canada, as part of the CanadaMark program which tracks the diamonds from the mine of origin.

  7. “We comply with the World Federation of Diamond Bourses (WFDB) Charter on Disclosure of Synthetic, Treated Natural and Natural Diamonds.

Please note:

We do not want to restrict members’ ability to summarise claims for marketing purposes, so while claims that are audited and certified by the RJC should include how they are implemented/verified as explained below, this does not mean that members must use the wording exactly as written on their certificate every time the claim is made or referred to. 

These are some examples of claims that are not considered provenance claims, and so cannot be audited as part of the provision:

  1. “All our diamonds comply with the Kimberley Process Certification Scheme and World Diamond Council System of Warranties” – these requirements are covered under a separate provision (Kimberley Process Certification Scope and World Diamond Council System of Warranties, provision 27) and so are not considered provenance claims

  2. “The diamonds herein invoiced have been purchased from legitimate sources not involved in funding conflict and in compliance with United Nations resolutions. The seller hereby guarantees that these diamonds are conflict free, based on personal knowledge and/or written guarantees provided by the supplier of these diamonds” – these requirements are covered under a separate provision (Kimberley Process Certification Scope and World Diamond Council System of Warranties, provision 27) and so are not considered provenance claims, even though you may be asked by Signet to make this statement. You can still include this statement on your invoices and it’s covered in your RJC audit, but under provision 27, and not as a provenance claim (provision 12).

  3. “Our jewellery is made to the best quality on the market” – this relates to product quality which is not covered by the provision which focuses on sourcing and provenance

  4. “Our watches are made in France” – this relates to location of manufacture and not sourcing practices or systems

  5. “We source all our materials responsibly.” – By encouraging claims that refer to the systems behind them, we hope to discourage open-ended and vague claims which can be left open to interpretation. This additional information makes transparent how the member sources responsibly, and those who wish to source from them are clear what ‘responsible’ means.
