To check if gold is 18K, the most reliable methods involve looking for official hallmarks or having the item tested professionally. You can also perform several at-home physical and chemical tests, though they are less conclusive.
How to check if 18K gold is real?
Check if your gold is real by performing the magnet test. Real gold will not attract a magnet. To test if 18k gold is real, hold it next to a magnet. If the magnet sticks to your jewelry, then it does not have a high percentage of gold but is made up of other, more magnetic metals.
How to test 18K gold with vinegar?

What is the fastest way to test gold?
Magnet. This is a fast, non-desctructive test that works surprisingly well. Gold isn't magnetic, so if your piece is attracted by the magnet, you know it's fake. Like all tests, it won't catch every fake, but it's a really fast and effective test you can do at home.
Will 18k gold sink or float in water?

Does 18K gold turn black with vinegar?

With that said, if a neodymium magnet is attracted to the gold or silver, that means that it contains trances of other metals and is not pure. However, this test is not entirely foolproof. For example, if the item is made from aluminum or copper, it will also not be attracted to a neodymium magnet.
What will gold not stick to?
