A headpin is a straight length of wire fitted at one end with a flat disc, ball, or decorative stop that prevents threaded components from sliding off. It is one of the most elementary findings in jewellery assembly, serving as the armature onto which beads, gemstone briolettes, pearls, or other drilled components are strung before the open end is worked into a connecting loop. The result — a finished dangle or drop — can be attached to earring wires, chain links, clasps, or other findings to complete a piece.

Construction and Varieties

Headpins are produced in a range of gauges, typically between 20 and 26 AWG (American Wire Gauge), with finer gauges suited to delicate seed pearls or small gemstone beads and heavier gauges required where structural integrity is paramount. Standard lengths run from approximately 25 mm to 75 mm, though longer pins are available for multi-bead stacks. The stop end takes several forms:

• Flat-head pin — the most common type, with a simple hammered or stamped disc stop, analogous to a dressmaker's pin.
• Ball-end pin — terminated with a small round bead of the same metal, offering a neater finish when the stop is visible.
• Decorative-head pin — the stop is cast or stamped into a flower, star, or other motif, functioning as a design element in its own right.

Materials

Headpins are available in virtually every jewellery metal. Sterling silver and gold-filled wire are standard choices for finished jewellery intended for retail sale, offering durability and tarnish resistance appropriate to the price point. Fine silver (999) pins are occasionally used where maximum malleability is required for intricate wire-wrapping. Yellow, rose, and white gold headpins in 14 ct or 18 ct are specified for fine jewellery. Base-metal pins — brass, copper, or plated alloys — serve costume and craft applications but are unsuitable where prolonged skin contact may cause sensitivity reactions. Niobium and titanium headpins are produced for hypoallergenic requirements.

Working Method

After the desired beads or gemstone components are threaded onto the pin, the jeweller trims the excess wire to leave approximately 8–10 mm proud of the topmost bead. This tail is then bent at a right angle and formed into a closed loop using round-nose pliers — a technique known as a simple loop — or worked into a wrapped loop, in which the wire is coiled two or three times around itself before the loop is closed, producing a more secure and visually refined finish. The wrapped loop is strongly preferred for heavier gemstone drops, where the weight might otherwise open a simple loop over time.

Distinction from the Eyepin

The headpin's close relative, the eyepin, is identical in construction except that both ends are open: one end carries a pre-formed loop rather than a stop. Eyepins are used where a component must connect to findings on both sides — for example, in a linked chain of beads — whereas the headpin is suited to terminal dangles where one end must be closed.

Role in Gemstone Jewellery

In the context of fine gemstone work, headpins are frequently specified for briolette earrings, where a faceted drop — aquamarine, tourmaline, or sapphire, for instance — is suspended from a gold wire that passes through the briolette's top drill hole and is then wrapped to form the connecting loop. The headpin thus becomes the invisible armature that allows a gemstone's full silhouette to be displayed freely. The choice of metal, gauge, and finish should be consistent with the quality of the gemstone mounted: an 18 ct gold wrapped-loop headpin is the appropriate vehicle for a fine tourmaline briolette; a base-metal flat-head pin is not.
