A French hook — also widely known in the trade as a shepherd hook — is a simple, open-ended curved wire finding designed to pass through a pierced earlobe and suspend a pendant earring by gravity alone. Unlike lever-back, omega, or screw-back fittings, the French hook employs no mechanical closure; the natural curve of the wire and the weight of the suspended jewel together keep the fitting in place. It is among the most prevalent earring findings in contemporary fine and fashion jewellery, valued for its elegance of line, ease of use, and the unobstructed swing it allows a hanging gem or drop.

Anatomy and Form

The French hook is formed from a single length of wire — typically round in cross-section, though flattened or half-round wire is also used — bent into a continuous, gently elongated curve. The forward arc, which passes through the piercing, is smooth and polished to minimise tissue irritation. Behind the ear, the wire curves back and slightly downward, terminating in a short tail that acts as a passive retainer: the tail catches on the back of the earlobe, reducing the likelihood of the earring slipping free during ordinary movement.

The loop or eye at the base of the hook — the point at which the decorative element is attached — may be a simple open ring, a soldered closed ring, or a small bead-tipped ball end. The ball end, sometimes called a balled French hook, adds a minor tactile stop and a decorative detail visible from the front. The gauge of wire used in fine jewellery typically falls between 20 and 22 AWG (approximately 0.8–0.6 mm), fine enough to pass through a standard piercing without discomfort yet sufficiently rigid to maintain its shape under the weight of a pendant.

Materials

French hooks intended for fine jewellery are produced in the following metals:

• 18ct yellow, white, or rose gold — the standard for high-end fine jewellery; 18ct alloys offer a balance of colour richness, workability, and durability.
• 14ct gold — common in the North American market, offering greater hardness and slightly lower cost while remaining hypoallergenic for most wearers.
• Sterling silver (925) — the dominant material in fashion and artisan jewellery; susceptible to tarnish and, in some individuals, to sensitivity reactions from copper content.
• Platinum — used in bespoke and high-jewellery contexts; its density and biocompatibility make it ideal, though the additional weight of the hook itself is a minor consideration when balancing a heavy drop.
• Niobium and titanium — employed for clients with metal sensitivities; both are highly biocompatible and may be anodised to produce colour without coatings.

Gold-filled and gold-plated brass hooks are standard in the fashion jewellery sector but are not considered fine jewellery findings. Nickel-containing base-metal hooks are increasingly restricted in the European Union under the EU Nickel Directive (REACH Regulation), which sets limits on nickel release from items in prolonged skin contact.

Security Considerations

The principal limitation of the French hook is its open, gravity-dependent retention. The fitting offers no positive lock, and a sharp lateral movement, a snagged garment, or a loosely formed tail can result in loss of the earring. For this reason, many jewellers and clients opt for a small rubber or silicone earnut (also called an earring back or butterfly clutch) placed on the tail of the hook behind the earlobe, providing a secondary mechanical stop without altering the visible profile of the fitting.

In the context of fine jewellery set with significant gemstones, some makers and auction houses note the security advantage of lever-back fittings over French hooks. Lever-backs incorporate a hinged closure that snaps shut behind the ear, substantially reducing accidental loss. Nonetheless, French hooks remain preferred by many wearers for their lightness, their ease of insertion and removal, and the natural pendulum movement they impart to a hanging stone — a quality particularly prized in earrings set with faceted drops, briolettes, or articulated chandelier designs where the play of light depends on free movement.

Manufacturing and Finishing

French hooks are produced both by hand fabrication and by machine drawing and forming. In a workshop setting, a jeweller draws wire to the desired gauge, cuts a measured length, forms the primary curve over a mandrel, shapes the retaining tail, and finishes the tip — either by filing and polishing to a smooth taper or by fusing a small ball using a torch. The loop at the base is opened with parallel-jaw pliers (never round-nose pliers, which distort the wire's cross-section), the finding is attached, and the loop is closed flush.

Commercially, French hooks are stamped or drawn in high volumes and supplied to jewellers as ready-made components. Quality varies considerably: well-made commercial hooks have consistent gauge, a smoothly polished entry tip, and a loop that closes without a gap. Poorly finished hooks may have sharp wire ends, inconsistent curves, or loops that spring open under the weight of a heavy pendant — all points a bench jeweller should inspect before use.

Hallmarking practice for French hooks varies by jurisdiction. In the United Kingdom, findings below a minimum weight threshold are exempt from compulsory hallmarking under the Hallmarking Act 1973, though the metal standard of the hook should match that of the earring to which it is attached, and responsible makers stamp or hallmark the hook where size permits.

In the Trade

The term French hook is standard in North American trade usage; shepherd hook is more common in British and Australian trade contexts, though both terms are understood internationally. Some suppliers distinguish a French wire — a very fine, lightweight hook with a minimal tail, associated with delicate drop earrings — from a standard French hook, which has a more pronounced retaining curve. The distinction is informal and not universally observed.

When specifying French hooks for a commission, the relevant variables are metal, gauge, loop diameter (to match the gauge of the jump ring or bail on the pendant element), ball or plain tip, and whether an earnuts pack is to be supplied. For earrings carrying stones of significant value, it is good practice to advise the client of the security differential between open hooks and locked fittings, and to document that advice.
