How to Test Gold Purity at Home
There are simple ways to check whether gold is real, but home tests have limits. Learn the magnet test, the hallmark check and why an acid or electronic test is best left to a jeweler.
Quick checks you can do at home
Start by looking for a hallmark such as 14K, 18K, 585 or 750, and check the weight and feel. Real gold is heavy, does not stick to a strong magnet, and does not discolor skin. These checks can flag obvious fakes, but they cannot prove purity. Shop hallmarked gold jewelry.
Home test limits
| Test | What it shows | Limitation |
|---|---|---|
| Hallmark | Claimed karat | Can be stamped on fakes |
| Magnet test | Non-magnetic | Gold plated passes too |
| Weight check | Density feel | Needs experience |
| Scratch test | Surface color | Damages the piece |
| Acid test | Karat range | Needs skill, acid kit |
When to see a professional
If a piece is valuable, antique, or you need a certified result, take it to a jeweler for an electronic or acid test. Never file or scratch a fine piece just to test it at home. Ask us to verify a piece if you are unsure.

Does real gold stick to a magnet?
No. Pure gold is not magnetic; a strong magnet will not hold real gold.
What do gold hallmarks mean?
Numbers like 585 and 750 show parts of gold per thousand; 14K equals 585, 18K equals 750.
Is the scratch test safe for jewelry?
No. It removes a little gold and can damage the piece, so leave it to a professional.
