Responsible Jewellery Council

The Responsible Jewellery Council (RJC) is the world's leading standard-setting organisation for the jewellery and watch industry. Founded in 2005 by 14 organisations including De Beers, Tiffany & Co., and Cartier, it unites over 2,100 companies across the entire global watch and jewellery supply chain to promote responsible practices and ethical standards. Members follow one or more of three standards: the Code of Practices (COP), Chain of Custody (COC), and Laboratory Grown Material Standard (LGMS). The RJC advances trust, transparency, and sustainability, and its standards support the UN 2030 Agenda and the 17 Sustainable Development Goals.

The Responsible Jewellery Council was founded in 2005 by 14 pioneering organisations including ABN AMRO, BHP Billiton Diamonds, Cartier, CIBJO (World Jewellery Confederation), the Diamond Trading Company (part of De Beers Group), Diarough, Jewelers of America, the UK's National Association of Goldsmiths, Newmont Mining, Rio Tinto, Rosy Blue, Signet Group, Tiffany & Co., and Zale Corporation. Today, its membership spans over 2,100 companies worldwide, representing every stage of the global watch and jewellery supply chain, from mine to retail. In 2025, the RJC celebrated its 20th anniversary and officially reached 2,000 members.
