Hallmarking Across the European Union
Hallmarking rules vary by EU member state, with some countries requiring independent assay and others allowing manufacturer self-marking, so marks are not uniform across the bloc.
No single EU-wide system
There is no single mandatory EU hallmarking law; instead, individual member states set their own rules, and some, like France and Italy, have distinctive national marking traditions.
The Convention on hallmarks
Many European countries participate in the Vienna Convention on the Control of the Fineness of Precious Metal Articles, which allows a Common Control Mark to be mutually recognised among member states, though not every EU country participates.
National variations
France uses distinctive maker and purity marks including an eagle's head for 18K gold on certain items; Germany typically marks fineness numerically; Italy requires a registered maker's mark alongside fineness. Always check the specific country of origin's convention.
