Why Hallmarking Is Mandatory
Precious metal hallmarking is a legal requirement, not optional. Each major market has regulators:
- USA: FTC requires purity marking. Violations: up to $10,000 per piece.
- UK: Assay Office mandatory hallmarking. Sterling must be stamped "925".
- EU: Varies by country, but 925 silver generally requires "925" or "Sterling".
- China: GB 11887 mandates purity marking.
Common Hallmark Symbols
| Mark | Meaning | Markets |
|---|
| S925 | 92.5% pure silver | China, general |
| 925 | 92.5% pure silver | International |
| Sterling | Standard sterling | US, UK |
| Ag925 | Element symbol + purity | Europe |
Export Pitfalls
Q: Can I stamp just my logo without purity?
A: No. Logo-only stamps without purity are "misrepresentation" under US FTC rules. Amazon will delist.
Q: Does gold-plated silver need a stamp?
A: Yes. Even with gold plating over silver base, you must mark "S925 overlaid" or equivalent.
Q: Where to stamp?
A: Rings inside band, necklaces on clasp, earrings on post back. Must be legible without ruining aesthetics.
