Gold is not magnetic. If a strong magnet grabs your chain, the chain is mostly not gold, or the clasp has a steel spring. If the magnet does nothing, that is a good sign but not proof, because many fake metals, like brass and copper, are not magnetic either.
How to do it
- Use a strong magnet, like a neodymium magnet. Fridge magnets are too weak.
- Hold it next to the chain links, not just the clasp.
- Watch whether the chain moves toward it or sticks.
How to read the result
| What happens |
What it likely means |
| Chain sticks firmly |
Not solid gold; likely steel or iron underneath |
| Only the clasp reacts |
Common; many clasps use a small steel spring |
| Slight pull |
Mixed metals; worth testing |
| No reaction |
Could be gold, or a non-magnetic metal like brass |
What should I check next?
Look for a karat stamp, check worn areas for a different color underneath, and have it tested. See How to Tell if Gold Is Real and How Jewelers Test Gold.
