RJC Chain of Custody
The Responsible Jewellery Council (RJC) is a standard-setting organisation for the jewellery and watch industry.
The RJC Chain of Custody certification is applicable to gold and platinum group metals, and is designed to promote traceability and give assurances on how products and materials have been sourced and processed through the supply chain. The certification is voluntary for RJC member companies, which may undertake it once after they have been successfully certified against the RJC Code of Practices.
