A cable chain is a jewellery chain composed of uniform oval or round links connected in an alternating series, each link passing through the next at a right angle to its neighbour. The resulting structure closely resembles the heavy iron chain used in maritime anchor cables — the origin of the name — and is among the oldest and most widely produced chain constructions in the goldsmith's repertoire. Its combination of structural simplicity, visual clarity, and adaptability across metals and gauges has made it the default chain form against which most other styles are measured.

Construction

Each individual link in a cable chain is formed from a length of wire drawn into an oval or circular shape and soldered or laser-welded closed. When assembled, successive links are oriented perpendicular to one another, so the chain lies flat and flexible in any direction. This perpendicular alternation distributes tensile stress evenly along the length, giving cable chain a strength-to-weight ratio that suits everyday wear.

Gauge — the diameter of the wire from which each link is formed — determines the chain's visual weight and mechanical strength. Fine jewellery pendant chains are commonly produced in gauges as delicate as 0.5 mm, while statement necklaces and men's chains may use wire of 2 mm or heavier. Link dimensions (width and length) are equally variable; a link whose length is notably greater than its width produces the elongated cable variant, while links of near-equal dimensions yield the rounder profile sometimes called round cable.

Principal Variants

• Flattened cable: Links are passed through a rolling mill after assembly, compressing them into a flat profile that increases surface reflectivity and gives the chain a ribbon-like appearance.
• Twisted cable: The assembled chain is gripped at both ends and rotated, imparting a helical twist to each link. The result catches light at multiple angles and adds textural interest without altering the underlying structure.
• Elongated cable: Links with a length-to-width ratio of approximately 2:1 or greater, producing a more open, ladder-like silhouette. Often used for pendants where the link spacing itself becomes a design element.
• Double cable: Two parallel cable chains joined by shared links at regular intervals, increasing width and visual presence.

Materials and Manufacture

Cable chain is produced in virtually every jewellery metal: yellow, white, and rose gold in 9, 14, and 18 karat alloys; platinum; sterling silver; and base-metal alloys for fashion jewellery. Italian manufacturers — particularly those based in Vicenza and the Arezzo district — have historically dominated high-volume fine cable chain production, developing automated link-forming and soldering machinery capable of consistent output at fine gauges. Handmade cable chain, formed link by link with round-nose pliers and soldered individually, remains a mark of bespoke or artisanal work.

Clasp compatibility is straightforward: the open oval end-link of a cable chain accepts spring-ring, lobster-claw, toggle, and box clasps without modification, which contributes to the style's prevalence as a ready-to-wear pendant chain supplied by jewellers and findings houses alike.

Relationship to Allied Styles

The rolo chain (also called belcher) is a close relative, distinguished by links that are circular rather than oval and typically heavier in gauge, giving a chunkier, more uniform silhouette. The anchor chain (or mariner chain) adds a central bar across each link, directly referencing the marine hardware from which cable chain takes its name. Both styles share the cable chain's alternating-perpendicular link orientation and are often grouped with it under the broader category of open-link chains.

In the Trade

Cable chain is sold by the metre or by the finished length, and findings suppliers list it by metal, karat, gauge, and link dimension. Its ubiquity means it functions as a commodity item at the lower end of the market, yet the same construction executed in heavy-gauge 18-karat gold or platinum commands significant value as a finished piece. For pendant settings in particular, a well-proportioned cable chain is considered the neutral, non-competing choice — one that supports the pendant without drawing attention from it.
