About the Assay Assured Organisation

Assay Assured is owned and administered by the Edinburgh Assay Office. The Edinburgh Assay Office was established by Royal Charter and our primary role has always been to guarantee the purity of precious metals.

Today our work centres on providing hallmarks for compliance with the 1973 Hallmarking Act. To do this we assay (check) and subsequently apply hallmarks to articles of gold, silver, platinum and palladium in compliance with national and international regulations. We have provided this service, without interruption, for over 550 years.

Protecting Online Jewellery Shoppers

Assay Assured and the Assay Assured Jewellery Retailers trustmark were launched in 2012 as means of allowing quality online jewellery retailers to promote their good practice. The scheme's primary purpose is to protect online jewellery shoppers from counterfeit and fake jewellery.
