In short
For a pendant worn daily, buy a Franco, box or wheat chain: they are dense, they do not kink and they do not twist. For a chain worn alone, a solid Cuban is the strongest common style and a rope the most sparkle per gram, but rope under 3 mm kinks and snags hair. Herringbone and snake look flat and sleek and are the two that a single bend can ruin. Whatever the style, solid beats hollow on every count except price.

The grams column (from our chain weight estimator) is why "strongest" is the wrong question. A Cuban is strong because at 4 mm it carries more metal per inch than anything else on the list; a Franco of the same width has about twice as many interlocking joins as a Cuban, which is where its refusal to twist comes from. Rope is the light one: same width, a fifth less gold than Cuban, and its strength is spread across many thin wires, any one of which can catch.
Chain weightGrams and value by style, width and lengthOpen calculatorSolid, hollow and semi-hollow: how to tell
Weight is the test. Divide the stated grams by the length in inches and compare with the chart: a 4 mm Cuban at 20 inches should weigh about 26 g solid; at 13 g it is semi-hollow, at 8 g it is hollow. Sellers who list width and length but not weight are usually selling hollow, and "lightweight" in a title means the same thing. In the hand, a hollow chain feels like plastic for its size, dents when pressed with a fingernail at a link, and shows a seam or a flattened tube shape at the cut end of a link under magnification.
Semi-hollow chains, made from tubing thick enough to resist dents, are a fair compromise for a wide look in 10k or 14k; fully hollow chains at 6 mm and above are a look, not a chain, and should be priced accordingly. Neither kind can be reliably resoldered once a link splits, because there is no solid metal for the solder to grip.
What actually breaks a chain

Chains rarely snap in the middle. They fail at the clasp and the jump ring next to it, because that is where the metal is thinnest and moves most; a lobster clasp on a solid ring beats a spring ring, and a chain that has been repaired once has its weak point moved to the solder joint. The second failure is the kink: a link bent out of plane. Ropes and herringbones kink because their structure depends on every element lying in place, and a kinked rope under 3 mm is usually not worth the jeweler's time. Box, wheat, Franco and Cuban links hinge in only one or two planes, so a snag turns them rather than bending them.
Hollow chains fail their own way. Made as tubes or stamped shells to give a wide look at a third of the weight, they dent when pressed, and a dented hollow link cannot be resoldered cleanly because there is nothing to solder to. A hollow rope or Cuban at a bargain price is fine as a look; it is not fine as a chain for a heavy pendant or a chain you plan to keep for decades.
Which chain for which use

Your first gold chain
A 3 mm rope or a 3.5 to 4 mm Cuban at 20 to 22 inches in solid 14k. Both are visible, both are repairable, both hold a pendant later, and both resell at melt if tastes change.
A chain worn alone
Cuban or Miami Cuban at 5 mm and up for a flat, heavy look; rope at 4 mm and up for sparkle; mariner for the same weight with a different pattern. All three are sold in the widths that make a statement, and all three are easy to repair.
A chain for a pendant
Franco, box or wheat. They stay still, keep the clasp at the back and do not twist under the pendant's weight. Chain width should also match: a bail opening at least half a millimeter wider than the chain, and a chain heavy enough that the pendant does not lever the links open, which is roughly a chain at least as heavy as the pendant for anything over about 10 grams. The strength guide ranks the styles by what breaks and matches pendant weight to a minimum chain in grams.
Chain widthMillimeters drawn to scale next to a quarterOpen calculatorLayering
One textured chain with plain ones: a rope with a cable and a box at 2 inch length steps. Two ropes twist together; two Cubans clatter.
Sleeping and sport
Box, wheat or Franco at 2 to 3 mm, or nothing. Rope, snake and herringbone are the ones people wake up having kinked.
Pendants and chains that pull hair

A pendant needs a chain that stays still under it, at the right length. Franco, box and wheat do; the pendant hangs where you put it and the clasp stays at the back. Rope and cable let the pendant slide and rotate, and the clasp migrates to the front.
Chain lengthWhich length sits where on youOpen calculatorHair gets pulled by chains with small open gaps that hinge, which is why fine ropes and figaros with small links are the usual culprits and why box, snake and wheat almost never are. Men with beards report the same about heavy Cubans against the chin; the fix is a shorter chain or a different length, not a different style.
Cost by style
Retail price is gold weight times a multiple for labor and margin, and both parts vary by style. Weight: at the same width a Cuban carries the most gold and a rope the least, so a rope gives the biggest look per dollar of metal. Labor: machine-made cable, rope and box are cheap to make; Miami Cuban and Franco need more finishing and command a higher multiple; hand-assembled Cuban and byzantine chains cost most. At today's 14k melt of $82.92 per gram, a 26 g solid 4 mm Cuban holds $2,131.04 of gold, and a fair retail price for a machine-made Italian chain sits around twice that; three times or more is paying for a brand.
Cleaning and storage differences

Solid chains of any style go into warm water with a drop of dish soap and a soft brush; a home ultrasonic cleaner is fine for plain gold chains and bad for hollow ones, which can trap water, and for plated ones, which it strips. Store chains clasped and hung, or laid flat in separate pouches: a rope or fine cable left loose in a box will knot, and untangling a knotted rope is how most kinks happen.
Questions people ask
What is the strongest gold chain for a pendant?
A solid Franco, box or wheat at 2.5 to 3 mm for pendants up to about 15 grams, a 4 mm Cuban for anything heavier. All four hinge in one or two planes, so a snag turns them instead of bending them, and the pendant hangs where you put it with the clasp at the back. Rope holds weight but twists under it, and thin rope kinks.
What kind of chain does not kink?
Franco, box, wheat, Cuban and mariner. The ones that kink are rope under 3 mm, snake, and herringbone, and herringbone creases for good. A kinked rope over 3 mm can sometimes be worked straight by a jeweler; under 3 mm it is rarely worth the labor, and the kink comes back.
Franco chain vs Cuban link: which is better?
Franco for a pendant and for wearing under a shirt: it is a four-sided weave with roughly twice the interlocking joins of a Cuban at the same width, so it neither twists nor kinks and lies flat. Cuban for a chain worn on its own: a wider look, about a fifth more gold per inch than rope at 4 mm (1.285 g against 1.04 g), and a single link that any jeweler can resolder, which a Franco cannot. Hollow versions of either lose most of these points.
Are snake chains durable?
Against tangling and hair, yes: the segments interlock into a smooth tube with no gaps to catch anything. Against a sharp bend, no: one hard fold kinks it permanently, because every segment depends on its neighbors lying in line. Snake is for light pendants and careful wear, not for sleeping in or for a 20 gram medallion.
Can you fix a herringbone chain?
A mild crease can be flattened by a jeweler with a burnisher and will still show a little; a sharp fold breaks the flat woven links and cannot be restored. Treat herringbone like a ribbon: hang it, never drop it in a pouch, take it off before bed. It is the one style where the repair often costs more than the chain.
Is a box chain or cable chain better?
Box for pendants: square links that do not twist, hold weight and keep the clasp at the back. Cable is lighter and cheaper for the same width and fine for small pendants, but fine cable knots in a drawer and lets a pendant rotate to the side. At 1.5 mm and below, box is the safer buy.
What chain does not turn your neck green?
Any solid 14k or 18k chain, in any style. Green comes from copper in brass under worn plating, or from 10k with a lot of copper against acidic sweat; it is a metal question, not a link question. A plated Cuban marks a neck as surely as a plated rope once the film is gone.
