How to Tell if a Cuban Link Chain Is Real: Step-by-Step Guide

on Apr 24, 2024

If you want to look classy while adding a luxurious touch to your style, a Cuban link chain might be the right pick.

While there are plenty of high-quality gold Cuban link chains available on the market, you may also come across some fake chains that often look real.

To benefit from the durability and strength of a Cuban link chain, it’s important to determine its authenticity. So, how to tell if a Cuban link chain is real?

Whether you’re a jewelry enthusiast or this is your first time buying a Cuban link chain, this detailed guide will walk you through the steps to distinguish a real gold chain from a fake one. 

How to Check the Authenticity of a Cuban Link Chain

Checking the authenticity of a Cuban link chain is a pretty straightforward task. You don’t need any fancy tools or professional equipment to spot a fake Cuban chain.

Here are some quick, easy, and effective ways to determine whether a Cuban link chain is real or fake. 

Check the Weight and Thickness

Gold chain on a scale

Weight and thickness are significant factors when determining the authenticity of a Cuban link chain.

Cuban chains made of real gold are quite heavy as gold has a density of 19.32 g/cm 3 . This explains why gold is heavier than silver, copper, aluminum, zinc, or other base metals with lower density values.

Plus, the individual links in a real Cuban chain are thick and closely packed together, adding some extra weight to the chain.

That being said, the very first thing you should do when buying a Cuban chain is check its weight and thickness by holding it. If the Cuban link chain feels lightweight and the links are spaced far apart, the chain is probably a fake.

It’s recommended to double-check by measuring the weight of the chain and using a multi-factor approach for accurate results. Don’t forget to consider whether the chain is made of solid or semi-solid gold as this will affect its weight. 

Check the Clasp

The next step is to carefully observe the clasp. Genuine gold chains are typically stamped with hallmarks, indicating purity, also known as the karat weight of gold. Look for the hallmarks, such as 14K, 18K, 585, 750, etc. If there are no markings on the clasp of your Cuban chain, it may not be made of gold.

While hallmarks on gold jewelry act as a form of consumer protection, some manufacturers use fake markings. Therefore, you should explore other authentication methods to ensure the quality of your Cuban link chain.

Additionally, the clasp on a real Cuban link chain should be sturdy and secure. However, you should still be able to easily open and close it. If the clasp feels flimsy or cheap and it’s also difficult to clasp and unclasp, the chain is most likely a fake.

Conduct an Acid Test

An acid test is a more accurate and reliable method for determining the authenticity of gold jewelry. However, it requires a very careful approach while following the safety precautions.

After preparing the area, get a pair of nitrile gloves and safety goggles. Next, make a tiny scratch or mark on a less visible part of the chain. Finally, apply a small drop of nitric acid to the mark and observe.

If nitric acid dissolves the mark, the chain is made of fake gold or the purity of gold is too low (less than 10K). If there are no reactions, fizzing, or discoloration, then your Cuban link chain is made of real gold.

Keep in mind that an acid test can potentially damage your precious gold chain when conducted incorrectly. Therefore, it’s crucial to have the test done by a professional or be extra careful when using this method for authenticating your Cuban chain.

Perform a Magnet Test

Performing a magnet test is a perfect alternative if you don’t have access to nitric acid or prefer using a safer method.

Fun Fact: Real gold is non-magnetic, meaning that it won’t stick to the magnet. Fake gold, on the other hand, is made of other base metals that are magnetic and easily stick to the magnet.

To do a magnet test, carefully move the magnet close to the chain until they are almost touching and run it over the chain. A fake Cuban chain will stick to the magnet, whereas a real one won’t be attracted to it. If the chain moves just a little bit, it’s totally fine.

Cuban link chains made of 10K, 14K, and 18K gold won’t be pulled toward the magnet. If you notice that the clasp of your chain is attracted to the magnet, don’t freak out. As pure gold is soft, clasps are often made of lower-purity gold and other magnetic base metals for added durability.

Observe the Color and Discoloration

Observing the color and discoloration of gold is an effective method for differentiating between a fake Cuban link chain vs a real one.

Genuine gold jewelry maintains a consistent color without tarnishing or discoloration. A uniform, rich color across the length of the chain indicates real gold.

Contrarily, imitation gold or gold-plated Cuban chains may show signs of wear and discoloration over time.

However, lower-karat gold chains may also tarnish, especially when being exposed to water or harsh chemicals. This is due to the reactive nature of other metals in gold alloys.

Seek Professional Appraisal

Are you still wondering how to tell if a Cuban link chain is real or fake? Then seeking a professional appraisal is the most reliable way of receiving a definitive assessment.

Expert jewelers and appraisers use special tools and advanced equipment to accurately determine gold authenticity. These evaluations often include a combination of the tests discussed in our comprehensive guide and go beyond the scope of DIY testing methods.

Consulting a professional appraiser is essential if you need a detailed and accurate authentication of your gold chain. By carrying out a thorough appraisal, jewelers can also help you determine a fair price based on the market value, just in case you decide to sell your Cuban chain.

Note that finding a reputable jewelry appraiser is crucial for receiving accurate documentation. Ensure that the selected appraiser has a strong reputation and proper qualifications. Ideally, a professional appraiser should also be certified by an authorized organization.
