Edinburgh Assay Office

Protecting consumers, assuring quality, and building trust. We are a not-for-profit statutory instrument. Our purpose is to provide an independent third-party guarantee of precious metal fineness for the jewellery industry. Through our expertise in testing, verification, and our long standing role in the design and application of industry standards, we ensure that every item bearing our hallmarks meets with the requirements of the UK Hallmarking Act and applicable international standards. We safeguard consumers interests, by advocating for transparent product descriptions, pre-market testing, and post market surveillance and traceability systems. We aim to help create and sustain a marketplace where consumers are empowered to make informed choices, and retailers can compete on a level playing field.
