Sheffield Assay Office - The only organisation of its kind to achieve official RJC certification

In 2020 Sheffield Assay Office will complete its first full year of official certification by the Responsible Jewellery Council.

The Responsible Jewellery Council helps companies of all sizes, throughout the jewellery supply chain, to meet the rising ethical demands of peers, consumers, financial institutions and civil society and is a gateway to sustainable growth for businesses.

As the only organisation of its kind in the UK to have achieved this principal status, the independently certified award has helped Sheffield Assay Office secure important contracts with customers who are committed to responsible sourcing and supply chain due diligence, as well as being keen to address sustainability best practices and align with the 17 United Nations Sustainable Development Goals.

After surmounting a rigorous audit process, Sheffield Assay Office has worked to adopt and adhere to the RJC's Code of Practice an will continue to do so throughout the three year certification.

Assay Master and Chief Executive, Ashley Carson said "Business practices covered by the Code include Legal Compliance, Financial Accounts, Non-discrimination, Employment Terms, Community Development, Health & Safety and Environmental Management, and our employees are actively encouraged to put forward ideas to improve environmental performance and Health & Safety standards. Currently, over 33,000 sheets of paper per year are being saved by having implemented a paperless XRF results system and we continue to improve information for visitors and contractors working on-site."

The Sheffield Assay Office was established in 1773, under an Act of Parliament and today the company assays and hallmarks the precious metals - silver, gold, platinum and palladium. Sheffield Assay Office is one of only four UK assay offices who all work to uphold the Hallmarking Act of 1973 and continue to ensure consumer protection for customers purchasing precious metals.
