and luxury shine, is one of the most counterfeited jewellery styles worldwide. Spotting a real one isn’t just about looks—it’s about craftsmanship, weight, and detail.

1️⃣ Check the Clasp – The First Sign of Quality
A chain’s clasp tells you more about its authenticity than you think. A genuine Cuban link chain always has a sturdy, weighty clasp that snaps shut securely.
Whether it’s a box clasp, a lobster clasp, or a custom lock—
- it should close firmly,
- never feel wobbly or hollow,
- and include a small hallmark like 14K, 18K, or 925.
If the clasp feels light, rattly, or too smooth to be true, it’s likely not solid gold. Many counterfeiters copy the link pattern but use cheap clasps to cut costs.
A real chain’s clasp is tight, seamless, and perfectly integrated with the links.
2️⃣ Examine the Links – Perfection in Every Curve
Cuban link chains are famous for their interlocking oval-shaped links that lay flat and reflect light evenly.
Authentic ones have:
- Uniform size and spacing across all links,
- Smooth edges that won’t snag your clothes,
- Perfect alignment when laid flat.
Run your fingers along the surface—it should feel fluid and buttery, not gritty or uneven.
If you’re learning how to spot genuine Cuban link chain craftsmanship, focus on precision: real Cuban links look like continuous golden waves, not twisted ovals.
3️⃣ Feel the Weight – Gold Has Gravity
One of the simplest but most reliable tests is the weight test.
Gold is a dense metal; even small chains feel heavy for their size.
- A solid gold chain will drop with noticeable weight when held.
- A fake or plated chain often feels airy and hollow.
Compare the weight with the manufacturer’s specs (many jewellers list grams per length).
If a 20-inch chain feels suspiciously light, it’s probably not authentic.
A real Cuban link chain always feels strong, sturdy, and substantial in your hand.
4️⃣ Look for Hallmarks and Engravings
Every genuine gold or silver chain has hallmarks that identify its metal content.
Look for stamps like:
- 10K, 14K, 18K for gold purity,
- 925 for sterling silver,
- or branded marks such as “TIADIEM,” “ITALY,” or “MADE IN MIAMI.”
Real hallmarks are engraved cleanly, not printed or laser-etched unevenly.
If you can’t find any markings—or if they’re faint and crooked—walk away.
5️⃣ Do the Magnet & Acid Test (Safely)
Gold is non-magnetic.
If your chain sticks to a magnet, it’s not real gold. This quick test is one of the easiest ways to spot a genuine Cuban link chain from a fake.
For deeper verification, jewellers use an acid test to determine the karat purity.
⚠️ Avoid DIY acid kits unless you’re experienced—they can leave permanent marks on your jewellery.
When in doubt, visit a professional jeweller for a quick, safe authenticity test.
6️⃣ Study the Shine & Colour
Real gold has a warm, deep lustre, not a cheap mirror shine.
Fake gold often looks too reflective, too yellow, or too dull.
A true Cuban link chain glows softly under both daylight and indoor lighting.
18K gold tends to have a richer tone, while 14K is slightly paler—but both maintain that unmistakable golden warmth.
If you notice fading colour near the clasp or edges, it’s likely just gold-plated.
7️⃣ Inspect the Craftsmanship – Small Details Matter
Luxury Cuban link chains are handmade or machine-finished with extreme precision.
Inspect for:
- Smooth joints between links,
- Even curvature and consistent polish,
- No glue, gaps, or uneven soldering.
Poor-quality imitations often have visible weld points or uneven alignment where links meet.
Real chains move like liquid metal—flexible yet solid.
8️⃣ Buy Only from Trusted Retailers
Even a beautiful chain can be fake if it comes from an unreliable seller.
To ensure authenticity:
- Purchase only from verified jewellers or official websites.
- Check for certificates of authenticity.
- Read verified customer reviews.
- Avoid too-good-to-be-true discounts.
