How to Test Gold With a Magnet

Magnets can be used to quickly determine whether a piece is genuine or fake. The test only takes a few minutes and can save you money on purchases. But be wary: this technique may not always work due to variations such as gold being coated with non-magnetic metals or constructed using materials that contain magnetic properties; therefore it would be wise to conduct multiple tests before making important purchases.

Neodymium magnets provide more accurate results and should be preferred over standard refrigerator magnets when conducting this testing. They can detect even trace amounts of other metals in gold.

Try scratching the jewelry against a ceramic surface. Real gold will leave a yellow stain; counterfeit pieces can leave dark marks.

One effective method for verifying whether or not your gold is real is to apply a drop of nitric acid directly onto it, which will dissolve any base metals other than pure gold and reveal whether or not your piece is indeed authentic.

Rub your jewelry on a dark and hard surface, such as a blackstone. If the mark disappears, this could be evidence that it is genuine gold.

Nitric and nitrohydrochloric acids can both be useful in performing this test. Simply apply several drops of each to a dark surface and rub your jewelry until a visible mark appears on it.

This test may not provide an exact assessment, but it can still help identify whether your jewelry contains real gold. Keep in mind, though, that this method may not work effectively on fine pieces as its use could potentially damage or discolor them.

Vinegar can be an extremely helpful way to conduct such tests. If you have gold jewelry, vinegar can either make it shine brighter or cause it disintegrate.

Use a small, lightweight neodymium if you need to test jewelry of a size that is not too large. These magnets are available at most home improvement shops and can accurately determine its purity.

If you do not have a magnet handy, rub a coin on your gold piece. If it sticks to the magnetic surface, it is likely fake.

The best way to determine whether your gold jewelry is fake or authentic is using various testing methods. Here are seven strategies you can employ when testing its authenticity.

Scratch Your Gold against a Ceramic Plate

When you scrape a ceramic plate, real gold will leave behind brownish or yellowish streaks; fake jewelry will leave darker streaks.

Try a salt-and-water test. Fill a cup or glass with warm water, place your gold in the center, and allow the test to run for at least 8-10 minutes to help identify whether or not your jewelry is genuine. This should provide an accurate representation of its authenticity.
