Convention Marks
As an alternative to the traditional UK Hallmarks articles may be marked with a Convention Hallmark which may have been applied by any one of the countries included in the International Convention on Hallmarking.
The United Kingdom has been a signatory to the International Convention on Hallmarks since 1972. This means that UK Assay Offices can strike the Convention Hallmark which will then be recognised by all member countries in the International Convention. Conversely, Convention Hallmarks from other member countries are legally recognised in the UK. Articles bearing the Convention Hallmark do not have to be re-hallmarked in the UK.
