This robust metal stamp precisely inscribes "STERLING" onto your silver pieces, fulfilling UK hallmarking requirements with a single, confident strike.
What it does
Engineered for clean, deep impressions, this straight punch bar transfers the "STERLING" mark directly onto your metal. Its hardened steel construction ensures the raised characters remain sharp through repeated use, delivering a consistent, legible debossed mark on sheet, wire, or finished items. The balanced design focuses hammer force for optimal striking efficiency.
How to use it
- Position the stamp firmly on your workpiece.
- Strike the punch squarely with a jewellery hammer.
- Wipe clean after use for longevity.
Who it's for
Essential for UK silversmiths and jewellers needing to legally mark their sterling silver creations. This tool streamlines the hallmarking process, replacing less precise methods. It's also ideal for advanced jewellery students and serious hobbyists seeking professional-standard results for their work.

Common questions at the bench
What metal does this punch work on?
Our steel letter, number, and design punches are heat-treated to strike non-ferrous metals: silver (sterling, fine), copper, brass, bronze, aluminium, gold. Striking hardened steel will damage the face. For pewter and very soft alloys, use light strikes.
What size impression do I need?
1–2 mm for ring shanks and small pieces (initials, hallmark-style); 3–4 mm for pendant backs and signed plaques; 5 mm+ for presentation pieces and stamped jewellery components. Bigger is not always better — a clean small mark reads better than a struggle with an oversized one.
What do I strike it with?
A 1–2 lb brass mallet on a polished steel bench block. Do not use a steel hammer — it will deform the punch over time. One firm strike beats two soft ones for a clean impression.
How do I keep the punch sharp?
Polished punches stay sharp for thousands of strikes if you are hitting cleanly on a flat block. If the face starts blurring impressions, polish lightly with 600-grit emery, then a buffing mop on a polishing motor. Replace before the face deforms further.
