How can you tell if a chain is gold plated?

Acid test.

An acid test can reveal the karat of solid gold jewelry, but it can also show whether jewelry is solid gold or gold-plated. With an acid test, a small sample of the jewelry is removed and exposed to acid to induce a color change. The resulting colors indicate which type of metal the jewelry is made of.

How do you test gold with a lighter?

Real, pure gold, when exposed to the flame, will get brighter after a while as it gets hotter, but will not darken. Fake gold pieces, such as fool’s gold (actually pyrite, an iron sulfide) and pieces made of brass, iron, or copper alloys will darken or otherwise change color when exposed to fire.

Is the vinegar test for gold accurate?

If your gold piece turns black or green when the vinegar is on it, or if it starts to smoke or fizzle at all when the vinegar touches it, it is most likely not real gold. If your gold piece does not change colors and does not fizzle or react to the vinegar in any way, it is probably real.

Does a magnet stick to gold plated?

Gold and silver are not magnetic. So technically, a piece that is heavy gold electroplated might not register with the magnet. That is why it’s important to use this test in conjunction with other tests if you absolutely must be sure about whether or not your jewelry is solid gold.
