The International Convention on Hallmarks The International Convention on Hallmarks is an international treaty between contracting countries, which aims at facilitating the cross-border trade of precious metal articles. UK is a signatory to the International Convention. This means that UK Assay Offices can apply the Common Control Mark (additional optional mark) which will then be recognised by all member countries in the Convention. The member countries of the Convention are: Austria, Cyprus, Czech Republic, Denmark, Finland, Hungary, Ireland, Israel, Latvia, Lithuania, The Netherlands, Norway, Poland, Portugal, Slovak Republic, Slovenia, Sweden, Switzerland and United Kingdom. For more information about the International Convention Marks, please visit any of the UK Assay Office websites. The Wild One Jewellery Hallmark bears not only authenticity of your jewellery, but it is representative of the pride, hard work and dedication that goes in to creating every single piece. All precious metal articles exceeding the legal required weight limit will have been tested and hallmarked where legally required at Sheffield Assay Office. The Hallmark recognisable as a piece of Wild One Jewellery will bear these symbols: The Sponsors mark, the Fineness mark, the traditional Fineness symbol (Lion or Crown) and the Assay Office mark (Sheffield/Yorkshire Rose).
