The Responsible Jewellery Council, an international industry group committed to the implementation of responsible business practices in jewellery supply chains, is currently reviewing its core certification standard for its members. Ahead of the revision, the RJC invited public comments to which Human Rights Watch, along with 20 independent groups and trade unions, responded in a letter to the group’s standards committee. Amongst others, the organisations are calling for the standards to be brought fully into alignment with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High Risk Areas. The letter, as well as Human Rights Watch's comments on the 2018 Draft Code of Practices are available below.

In a February 2018 report, The Hidden Cost of Jewelry, HRW examined responsible sourcing in the jewelry industry and assessed the practices of 13 brands. Business & Human Rights Resource Centre invited the brands named to comment. Their responses are available here.
