How to Tell if a Gold Chain Is Real or Fake

You’ve found a gold chain you love—and the price seems almost too good to be true. Before you buy, it’s smart to pause and make sure you know exactly what you’re getting. Here are the most reliable ways to tell whether a gold chain is real or fake.

Check if It’s Gold-Plated or Solid Gold

One of the most common reasons a gold chain is inexpensive is that it’s gold-plated or silver vermeil, not solid gold. These chains have only a thin layer of gold over a base metal.

Examine the chain closely under good lighting, especially around:

• Clasps

• Edges

• High-friction areas

If you notice discoloration or a different metal showing through, the chain is likely plated. Gold-plated jewelry may look bright and shiny—sometimes even more yellow than solid gold—because the thin surface layer is often higher-karat gold.

However, beneath that surface is a non-gold metal, which greatly reduces the chain’s true value.

Look for a Karat Stamp

Authentic gold chains are typically stamped with their karat value, such as:

• 10K, 14K, 18K

• Or numeric markings like 417 (10K), 585 (14K), or 750 (18K)

These markings indicate how much pure gold is in the piece. Pure gold is 24K, but you won’t see 24K chains for everyday wear because pure gold is too soft.

If you see stamps like GP (gold-plated) or 925, the chain is not solid gold.

While stamps can occasionally be missing or faked, their presence is still an important first check.

Acid Testing: A Reliable Method

One of the most accurate ways to test gold is through acid testing. A jeweler can do this for you, or you can purchase a gold testing kit and perform the test yourself using proper safety precautions.

A small amount of metal is exposed and tested with nitric acid to determine whether it reacts. Real gold resists the acid, while base metals do not.

Why Magnet Testing Isn’t Reliable

Magnet tests are often suggested—but they’re not dependable. While gold itself is non-magnetic:

• Gold alloys may contain magnetic metals

• Some non-gold metals (like copper or zinc) are also non-magnetic

This can easily lead to false results, so magnet testing alone should never be trusted.

Final Thoughts

If you’re unsure about a gold chain’s authenticity, don’t guess. Look closely, check for stamps, ask questions, and consider professional testing. A reputable seller should be transparent about what they’re offering.

When you know what to look for, you can buy with confidence—and enjoy your gold chain knowing it’s exactly what you paid for.
