Sheffield Assay Office

There has been an Assay Office in Sheffield since 1773, when local silversmiths successfully petitioned Parliament for the right to assay silver in Sheffield. To \'assay\' means to test the precious metal content of an item and provides an independent assessment of quality and content. Today, The Sheffield Assay Office’s customers are global and the business has evolved to meet the demands of society and industry. Jewellery and items of precious metal are still assayed in their millions each year and bear the distinctive Sheffield \'Town\' mark, but Sheffield Assay office now has a world-wide reputation for cutting-edge analytical services.
