A Cuban link chain is a thick curb chain with rounded links pressed tightly together so it lies flat and looks almost solid. It is one of the strongest chain styles. When choosing one, decide the width, check whether it is solid, semi-solid or hollow, and look for a secure box clasp.
The Cuban, often called the Miami Cuban, is the chain people picture when they think of a men’s gold chain, and it is just as popular in finer widths for women. It is simple in design and easy to get wrong in the buying, because two Cuban chains that look alike in a photograph can differ enormously in how much gold they contain.
What a Cuban link chain is
A Cuban chain starts as a curb chain, whose links are twisted to lie flat. In a Cuban the links are thicker and rounder and are pressed close together, so the chain reads as one continuous band rather than a line of separate links. That dense interlock is what makes it one of the most durable, heavy-duty chain styles, and what gives it its weight. It is designed to be worn alone and can overwhelm a small pendant.
Construction and durability are described in Brilliant Earth’s chain guide.
Miami Cuban, Cuban link or curb: the names
“Cuban link”, “Cuban chain” and “Miami Cuban” all describe the same chain. Miami Cuban is the name most used in the United States, and some sellers use it for their heaviest, most tightly interlocked versions. Whatever the name, judge the chain on the same three things: width, construction and clasp.
Cuban vs curb chain
| Curb | Cuban | |
|---|---|---|
| Links | Uniform, twisted to lie flat | Thicker, rounder, tightly interlocked |
| Look | Flat, open links | Dense, almost solid band |
| Weight | Lighter | Heavier at the same width |
| Best for | Everyday, with or without a pendant | Worn alone, as a statement |
In the hand, the difference is easy to see. Lay the chain flat: a curb shows daylight between its links, while a Cuban’s links close up against each other with almost no gap. Run it through your fingers and a Cuban feels smooth and continuous; a curb feels like separate links. At the same width, the Cuban is the heavier and stronger of the two.
Cuban link chain sizes
Width is measured in millimeters across the chain and changes the look more than anything else.
| Width | How it reads | Usual lengths |
|---|---|---|
| 2 to 3 mm | Fine and understated; women’s everyday wear, layering, or carrying a small pendant | 16 to 20 inches |
| 4 to 6 mm | The classic everyday Cuban, visible without dominating; the most worn men’s width | 20 to 22 inches |
| 6 to 8 mm | A clear statement, worn on its own | 22 to 24 inches |
| 8 to 10 mm and wider | Heavy and bold; expensive in solid gold | 22 to 24 inches |
A chain looks wider on a slim neck and narrower on a broad one, so if you are between two widths, consider your build. Weight rises quickly with width, which affects both comfort and price, and construction matters as much as width: a semi-solid 7 mm chain can weigh less than a solid 5 mm one. A matching Cuban link bracelet usually looks best one or two millimeters narrower than the chain.
Solid, semi-solid or hollow
This is the decision that matters most. A solid Cuban is gold all the way through every link. A semi-solid Cuban has partially hollowed links, keeping the width and outline with less gold. A hollow Cuban is made of thin gold tubes. All three can be genuinely 14K. The karat tells you the purity of the alloy; the construction tells you how much of it you are buying.
Because a Cuban is all about substance, construction shows. A solid Cuban has the weight and the presence; it resists dents and can be repaired if it breaks. A semi-solid Cuban is a reasonable way to get a wide look for less money and less weight on the neck. A hollow Cuban is light, dents more easily and is hard to repair. Ask for the construction and the weight in grams before you buy any Cuban chain. Our guide to hollow vs solid gold explains what to look for.
How strong is a Cuban chain?
Very strong, in solid construction. The tight interlock spreads stress across many contact points, so a solid Cuban resists the wear and snags that break finer chains. The weak points are the same as on any chain: the clasp and the links nearest it. A heavy Cuban puts more load on its clasp than a fine chain, so the clasp should match.
The clasp
Many Cuban chains close with a box clasp, a flat tongue that slides into a box built into the last link so the clasp almost disappears. Look for a box clasp with a safety: a side latch or figure-eight that keeps the chain on even if the main clasp opens. Close the safety every time. Our guide to clasp types shows how box clasps work and how to tell when one needs re-tensioning.
Choosing a length
For men, 20 to 22 inches sits around the collarbone, and 24 inches falls lower on the chest. For women, 16 to 18 inches sits at or just below the collarbone. Wider Cubans look best a little longer, so they lie flat rather than standing up at the neck. Our size guide has a full length chart.
Caring for a Cuban chain
Clean it every few weeks with warm water, mild soap and a soft brush worked between the links, then dry it fully. Take it off to sleep, swim and lift weights. Store it laid flat. Have the clasp checked once a year, especially on a heavy chain.

Another name for the Cuban link chain, used widely in the United States, often for heavier, tightly interlocked versions.

You can, but Cuban chains are usually worn alone; a small pendant can look lost on a wide one.
