About RJC

The Responsible Jewellery Council is an international not-for-profit standards and certification organisation. It has more than 1100 Member companies that span the jewellery supply chain from mine to retail. RJC Members commit to and are independently audited against the RJC Code of Practices – an international standard on responsible business practices for diamonds, gold and platinum group metals.
The Code of Practices addresses: 

  • human rights
  • labour rights
  • environmental impact
  • mining practices
  • product disclosure
  • and many more important topics in the jewellery supply chain.

RJC also works with multi-stakeholder initiatives on responsible sourcing and supply chain due diligence. The RJC’s Chain-of-Custody Certification for precious metals supports these initiatives and can be used as a tool to deliver broader Member and stakeholder benefit. The RJC is a Full Member of the ISEAL Alliance – the global association for sustainability standards. For more information on RJC Members, Certification, and Standards please visit
