4 TESTS TO RECOGNIZE AUTHENTIC GOLD TO DO AT HOME
Introduction
When buying gold jewelry — especially vintage or second-hand — it’s important to know if it’s genuine gold. In this guide, you’ll discover 4 simple tests you can do at home to see if an item is actually gold . No professional equipment required!
1. Check the brand or hallmark (karat)
All genuine gold jewelry must have a hallmark indicating the carat:
750 (18K) , 585 (14K) , 375 (9K) , etc.
🔎 Where to look for the punch?
If you don't find the hallmark, it doesn't necessarily mean it's fake — sometimes wear and tear or artisanal provenance explain this — but it's still a first warning sign.
2. Magnet test
Gold is not magnetic .
All you need is a fairly strong magnet (the kind found in hardware stores or industrial refrigerators).
How to do:
💡 Please note : Some fakes are gold plated and contain magnetic metals inside.
3. Test with ceramics
All you need is an unglazed ceramic plate (the rough bottom of a dinner plate will do).
How to do:
- golden, it's gold
- black or grey, it is not real gold
Do not use too much force to avoid scratching the jewel.
4. White vinegar or lemon test
Real gold does not oxidize or change color when exposed to weak acids.
How to do:
✔️ Real gold: no change
❌ Fake or plated gold: may darken or leave a stain
Conclusion
These home tests are useful for an initial check , but they do not replace a professional inspection . If you have doubts about the value or authenticity of your jewelry, always rely on a certified jeweler or laboratory.
