The Responsible Jewellery Council (RJC) is the leading standards organization of the global jewelry and watch industry. It has more than 1,300 member companies that span the jewelry supply chain from mine to retail.

RJC Members commit to and are independently audited against the RJC Code of Practices (COP), an international standard on responsible business practices for diamonds, colored gemstones, silver, gold and platinum group metals. It addresses human rights, labor rights, environmental impact, mining practices, product disclosure and many more important topics.

RJC also works with multi-stakeholder initiatives on responsible sourcing and supply chain due diligence. Its Chain-of-Custody Certification (CoC) for precious metals supports these. Through the implementation of the COP and CoC, RJC members contribute towards the 17 Sustainable Development Goals of the United Nations 2030 agenda.

RJC is a Full Member of the ISEAL Alliance – the global association for sustainability standards. It has been a member of the United Nations Global Compact since 2009.
