The Responsible Jewellery Council has appointed Sara Yood and Eduard Stefanescu as the new co-chairs of its pivotal Standards Committee.

The Responsible Jewellery Council (RJC) has appointed two new co-chairs to its Standards Committee: Sara Yood and Eduard Stefanescu.
The Standards Committee is central to ensuring RJC’s Codes of Practice, Chain of Custody, and Laboratory Grown Materials standards remain robust, credible, and aligned with evolving global expectations for responsible business conduct. With expanding membership and increasing regulatory complexity, the committee’s work is more critical than ever.
Sara Yood, President and CEO of the Jewellers Vigilance Committee (JVC), is a recognized authority in jewellery industry regulations, responsible business conduct, and consumer protection. She leads the organization’s work on legal guidance, compliance, and integrity in the US jewellery market. Her expertise strengthens RJC’s commitment to alignment with international laws, due diligence frameworks, and high ethical standards.
Eduard Stefanescu, Sustainability Manager of C.HAFNER GmbH + Co. KG, is an industry leader in precious metals innovation and circularity. He oversees international operations in refining, recycling, and supply-chain integrity. A geoscientist by profession, his technical and sustainability expertise supports the Standards Committee’s mission to advance responsible sourcing, environmental stewardship, and transparency. He also chairs the European Precious Metals Federation’s Sustainability Platform and the German Precious Metals Federation’s Sustainability Working Committee.
John Hall, RJC’s Interim Executive Director, stated:
The Standards Committee is meeting in London from 16-18 December, where many new members will join to support the transition. The new appointments reflect RJC’s commitment to continuous improvement and a transparent, inclusive, and rigorous standard-setting process. All changes take effect on 1 January 2026.
RJC also welcomes a group of new committee members drawn from across the jewellery value chain, civil society, and consumer representation. Their combined experience strengthens the committee’s multi-stakeholder approach and reflects the breadth of expertise needed to shape globally credible standards.
New industry members include: Ben Ronca (Leach Garner), Donald Bray (Fura Gems), Melanie Mater (De Beers), Valerie Michel (Rosy Blue), Wafa Jaffery (DMCC), Alethea Inns (Gemological Science International), and Raluca Angel (Natural Diamond Council).
Non-industry members include: Antonino Serra Cambaceres (consumer), Chris Vandome (Chatham House), Abbi Buxton (Human Rights, Gender, Inequality Representation), Laure Williams (Richemont), Francesco Giunta (Heraeus), and Kesah Trowell (Watches of Switzerland).
