Hallmark Identifier
Identifying hallmarks is one of the most useful skills a collector can develop. These tiny stamps tell you where a piece was made, when it was assayed, and what metal it contains. Our Hallmark Identifier helps you decode these marks quickly and accurately.

What This Tool Does
This tool provides a searchable database of over 100 common hallmarks from Britain, France, Italy, and other major jewelry-producing countries. Each entry includes the mark's appearance, meaning, date range, and context for interpretation. The database focuses on marks you're most likely to encounter on vintage and antique jewelry.
⚠️ Important Limitations
Hallmarks alone don't authenticate a piece—they're one data point among many. Marks can be faked, added later, or misinterpreted. Some legitimate marks are too worn to identify clearly. This tool is educational and doesn't replace professional authentication. When significant money is involved, always seek expert verification.
