3mm vs 4mm Cuban Link chain

Hey there, fashion enthusiasts! Today, I am delving into the intricate world of Cuban Link chains, particularly the 3mm and 4mm varieties.

Now, I know measurements in millimeters might sound like a snooze fest, but trust me, they’re the secret sauce in picking out that perfect piece of bling.

Why Millimeters Matter in Jewelry

Before we jump into the nitty-gritty of our Cuban Link showdown, let’s talk millimeters. In jewelry, mm is king because it gives us the precision we crave.

Think about it: a tiny millimeter can change the whole vibe of a piece! And for those of us who didn’t grow up with the metric system, here’s a quick cheat sheet:

  • 1mm = just over 1/32 inch
  • 3mm = almost 1/8 inch
  • 4mm = 5/32 inch (just a tad over 1/8 inch)

Got it? Great! Now, let’s get to the fun part.

The main reason why they look similar is their width and weight.


A Cuban Link chain is made by creating a series of small, interlocking links.

The links are then joined together to form a larger chain.

The number of links in a Cuban Link chain can vary, but the most common length is 18 inches.

The manufacturing process begins with a length of wire being cut to size.

This wire is then fed through a machine that bends and shapes it into small, interlocking links.

Once all the links have been created, they are then joined together using a special welding process.
