How to test gold with vinegar

Vinegar is a versatile cleaner used around the house, in boats, cars, and in foods.

If you’ve ever wondered whether a gold piece is real gold or some other type of metal, you can find out without taking it to a jeweller or pawn shop. Using equipment and ingredients you already have, you can test the authenticity of gold with a very simple test conducted in your own kitchen.

Step 1:

Pour the white vinegar into your glass cup. Do not add water.

Step 2:

Place the gold ring into the cup of white vinegar.

Step 3:

Let the gold ring sit in the cup of white vinegar for approximately 15 minutes.

Step 4:

Remove the gold ring and rinse with water. Real gold will shine while fake gold will change colors in reaction to the ascetic acid.

Gold is a stable metal and does not react with oxygen corroding. Because it is stable, it will not change colors when exposed to vinegar.


This test won’t hurt your gold. On the contrary, vinegar is commonly used to clean gold jewellery.


Be aware that some gold jewellery may be marked 14k or 18k even though it is not real gold. This is a sly marketing tactic employed by some jewellery dealers.
