About this project

Every piece starts on a beach, not at a workbench. The shells get picked one at a time — shape, curve, and the way light catches the inside of the spiral all matter more than "matching" anything. No two ever come out the same, and that's the point.

From there it's low-temperature pewter (tin-based, easy to melt on a home stove) poured into hand-carved plaster or silicone molds shaped around each individual shell. Nothing is mass-produced or cast from a reusable master mold — every pour is one-off, which means every setting fits its shell and only that shell.

Process, roughly

  • Clean and dry the shell, then press it into casting sand or carve a plaster negative around it
  • Melt pewter (~170°C) and pour by hand — small batches, watched the whole time
  • Once cool, file and sand the rough edges, then polish
  • Set or bezel the shell back into its pewter cradle, add jump rings and a chain or cord

Why do it this way

It would be faster to buy blank bezel settings and glue shells into them. That's not really the appeal here — the slow part (finding the right shell, carving a mold that actually fits its exact curves, pouring metal by hand and hoping it flows evenly) is the craft. Every flaw, air bubble, or slightly uneven edge stays in the final piece instead of being sanded into uniformity.

Note: this is a test/demo project entry.
