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.

What to do: Hold the magnet up to the gold. If it’s real gold it will not stick to the magnet. (Fun fact: Real gold is not magnetic.) Fake gold, on the other hand, will stick to the magnet.

How can I test gold without a tester?
Place your jewelry on a table or hold it in your hand, pour some white vinegar on the metal directly (a dropper can also be used) if the metal of the jewelry changes its color, it is not pure gold and if it keeps shining then you have real gold in your hand.
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.
What is the symbol for gold plated?
Most other letter markings indicate that a piece is gold-plated or gold-filled. Gold-plated pieces may be marked ‘GP,’ ‘GE,’ or ‘HGE. ‘ ‘GP’ or ‘GE’ means the piece is electroplated with a thin layer of gold; ’18K GP’ would indicate a piece plated with 18 karat gold.
