How to Tell One Gold Chain From Another

Six structures cover almost every gold chain sold: cable, curb, figaro, rope, box and snake. What separates them is the shape of the link and how one link sits against the next. That decides how the chain lies on the skin, how it catches light, and — the part nobody mentions at the counter — whether a damaged one can be repaired at all.

The names are old and the trade uses them loosely. But every one of the six is recognizable from a photograph if you know which feature is doing the naming.

Six structures, and the one feature that names each

Read the table by the middle column. Most people try to identify a chain by how it looks overall, which is why two chains that behave completely differently get called the same thing.

The six structures at the same scale. Each one is a different answer to the same question: how do you make metal that bends in every direction but does not come apart?

Cable and curb are the same chain until one step in the making. Figaro is a cable or curb with its rhythm deliberately interrupted. Rope, box and snake are different constructions entirely, which is why they behave differently later.

Why a curb chain lies flat

The most useful thing to understand about chain is also the least discussed, because it happens in one step that takes seconds and is invisible afterwards.

A cable chain becomes a curb chain in one operation. Nothing is added and nothing is removed; the links are simply turned and pressed.

A cable chain is made of round links, each one sitting at right angles to its neighbors. Left alone it rolls. Put it on and by the end of the day it will have turned, showing you its edge rather than its face.

A curb chain starts the same way. Then the links are twisted so they share a plane, and the chain is pressed flat. After that, each link can only lie one way, and the chain has no choice but to sit against the skin. That is the entire difference. It is also why a curb chain of the same gold weight looks wider and reads heavier than the cable it started as.

The flattening also creates the flat faces that can be diamond-cut — shaved with a rotating cutter so each link carries a bright, mirror-flat facet. On a curb chain those facets all face the same direction, which is why a diamond-cut curb flashes as you move rather than glowing evenly. On a cable chain there is no shared plane to cut, so the same treatment scatters.

Thicker is not better made

A heavier chain has more gold in it. That is all it reliably tells you. A well-made 1.4 mm cable in solid 18K gold has had the same number of joins soldered as a 3 mm one, each one just as small and just as capable of being done badly. The thin chain is arguably the harder job.

What thickness actually buys is tolerance. A thicker link survives being caught on a jacket zip; a thinner one of the same construction may not. That is a real consideration, and it is a different one from workmanship. If a chain is going to carry a pendant — where the join at the top concentrates the load onto a few links — the tolerance matters more than the pattern does.

Two chains, two kinds of damage

This is the distinction that should decide the purchase, and it almost never comes up before one.

One of these can be opened, repaired and closed again by any competent bench. The other cannot, because the damage is to the band itself.

Cable, curb, figaro and box chains are assemblies of discrete links. If one fails, a jeweler cuts it out, fits a replacement and solders it shut. The repair is routine, the chain keeps its length, and if the joint is done properly you will not find it again afterwards.

Rope and snake chains are different. A rope is many small links locked into a spiral; disturb the spiral and the structure around the damage unwinds. A snake is a continuous jointed band, and once it has been kinked — folded sharply, caught in a drawer, slept in awkwardly — the kink is permanent. The band cannot be persuaded back into line, and the usual outcome is shortening the chain or replacing it.

None of which makes rope and snake bad chains. They do something the others cannot: a snake chain is the only one of the six that reads as a solid, continuous surface, which is exactly why people choose it. It simply asks to be stored flat rather than dropped in a bowl.

Five things to establish before buying

1. Which structure it actually is. Look for the naming feature, not the overall impression. A photograph is usually enough.
2. Whether it can be repaired. Link chains can. Rope and snake mostly cannot, which is worth knowing at the time rather than later.
3. Whether it will lie flat. Cable rolls. Curb, box and snake do not. This is a decision, not a defect.
4. The clasp and the ring beside it. The closure and the small ring next to it fail long before the chain does.
5. What it will carry. A chain bought bare and a chain bought for a pendant are different purchases, even at the same weight.

Where this works against us

We would rather sell you a chain you keep than one you replace, and that means saying the unhelpful thing: the chain that photographs best is often the one that repairs worst. Snake and rope have a density and a continuity that cable cannot produce, and both of them are less forgiving of ordinary accidents.

There is also a limit on what we can tell from a description. Two chains described identically — same construction, same width, same solid gold — can differ in how well the links are finished inside, where nobody looks. What we can do is tell you which questions the answer lives behind.

The choice gets easier once the chain stops being an accessory to something else. A 55 cm length in solid 18K gold carrying four graduated stones is doing the work that a pendant would otherwise do, which changes what you want from the structure holding it — and changes again the moment you start wearing two or three at once, where how each one lies against the next is the whole question.

Six names, six structures, one feature each. The chain that suits you is not the heaviest one available. It is the one whose behavior you will still want in three years, which is a different thing and a much easier question to answer once you know which six you are choosing between.
