Reference·Mandatory maker's mark

Italy

Italy doesn't use pictorial town marks — every piece instead carries its maker's registered number inside a starred polygon, struck by the maker under state supervision.

In the atlas: Ponte Vecchio Goldsmiths · Vicenza Gold District

The system

Mandatory maker's mark

The registered maker-number system was set up by Law 46/1968 and re-enacted by Legislative Decree 251/1999. Punches are sealed and audited by the Chambers of Commerce.

Mandatory maker's mark + fineness, under Chamber-of-Commerce oversight.
