Headpins are one of the professional jewelry designer's versatile trade secrets. Headpins can be used to make custom dangles with full-drilled stone, pearl, or metal beads. These short, straight 24 gauge (.50mm) metal wires come with a flattened 1.4mm nailhead at one end (2.5mm outer diameter, 1.5mm inner diameter). This head stops a bead from sliding off the pin; the flat disc has an unobtrusive profile that won't detract from the bead itself. Our 14Kt rose gold filled .50" headpins add color and professional flair to your jewelry designs.
