Diamond blanks in four sizes — 28.92 × 25.61 mm, 24.79 × 21.95 mm, 20.66 × 18.20 mm and 13.53 × 14.00 mm — sheared from sheet one strike at a time. Cut them as pendants, charms and earring components, as inlay pieces for mixed-media work, or as uniform bases for stamping and enamelling.

Die block and punches are hardened carbon tool steel; the compact 76 × 76 mm block tucks onto a crowded bench without giving up stability. Punches are ground sharp at the business end and bevelled for the mallet at the other. Brass or nylon mallet, non-ferrous sheet to 18 gauge (1.02 mm), a drop of cutting lubricant — that is the whole routine.

  • Fabricating diamond-shaped pendants, charms, and earring components.
  • Creating custom inlay pieces for metalwork or mixed-media projects.
  • Producing uniform blanks for subsequent stamping or enamelling work.
  • Cuts four distinct diamond shapes from non-ferrous sheet up to 18 gauge (1.02 mm).
  • Includes punch sizes (approx): 29x26mm, 25x22mm, 21x18mm, and 14x14mm.
  • Punches and die block are machined from hardened carbon tool steel for clean cuts.
  • Compact 76 x 76 mm (3 x 3 inch) die block fits easily on a jeweller's bench.
  • Punches are ground sharp on the cutting end and bevelled on the striking end.

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.
