Gold has been a symbol of wealth and prosperity for centuries. However, with the rise of counterfeits, it can be hard to tell if gold is real unless you know what signs to look for.
When it comes to buying gold, it’s essential to choose a reputable dealer. At Bullion Giant, we make it easy for you by offering gold bullion bars from LBMA-approved brands and thoroughly checking our coins for accuracy in weight, metal content, and authenticity.
So, whether you’re an avid collector or simply trying to assess a piece of inherited jewellery, we’ll walk you through six effective methods to test if your gold is real.
How to tell if gold is real
1. Test its size and weight
One of the simplest ways to check if your gold is authentic is by testing its size and weight. Real gold is dense and heavy compared to most other metals. To perform this test, use a precise scale to measure the weight of your gold item. Then, calculate its density by dividing the weight by the volume (you can find volume using water displacement). Gold’s density is approximately 19.3 grams per cubic centimetre. If your gold doesn’t match this density, it’s likely not real.
How to tell if gold is real with this method involves comparing the weight of your gold piece to known values. For example, if your gold ring is much lighter than expected, it could be a sign of a fake.
2. The magnet test
Gold is not magnetic, so using a magnet is an easy way to check if gold is real. Simply place a strong magnet near your gold coin, bar, or jewellery. If the piece is attracted to the magnet, it’s not real gold. However, if it remains unaffected, it’s a good sign that your gold is genuine.
Keep in mind that while the magnet test is useful, it doesn’t guarantee authenticity as some fake gold might be non-magnetic as well. Thus, combining this test with others is a strategic approach when determining how to test if gold is real.
3. The sound test
The sound test is another classic method to spot fake gold. When you drop or tap real gold, it produces a distinct, clear “ping” sound. This is due to gold’s unique acoustic properties. To perform this test, gently tap your gold item with another piece of metal or a hard surface. Listen carefully to the tone it produces.
A dull or hollow sound often indicates that the gold might be fake or mixed with other metals. On the other hand, if you hear a high-pitched, clear ringing tone, you’re likely dealing with genuine gold. This method, while not foolproof, can be a good indicator when used alongside other tests.
4. The ceramic test
The ceramic test is a straightforward and effective way to determine if your gold is genuine. Rub your gold item against an unglazed ceramic plate. Real gold will leave a gold streak, while fake gold will leave a black or green mark.
This test works because real gold is soft and malleable, and won’t easily scratch or discolour the ceramic. It’s a quick and non-evasive test that can be done at home.
5. Nitric acid test
The nitric acid test can be a bit more complex, but it’s a definitive method for verifying gold’s authenticity. This test involves applying a small amount of nitric acid to a scratch made on the surface of your gold item. Real gold will not react to oxidation, while fake gold or gold-plated items will change colour or produce a green or white residue.
To perform this test, you need a nitric acid testing kit, which can be purchased online or at jewellery supply stores. Remember to exercise caution and follow safety instructions, as nitric acid is corrosive.
6. The hallmark test
Finally, checking for hallmarks is a reliable way to verify if your gold is real. Genuine gold items usually have purity markings or hallmarks stamped on them. These markings can indicate the gold’s purity, such as 24K or 999.9 for pure gold, 18K, or 14K.
To use this test, examine your gold item for these hallmarks. Look for specific markings, including the producer’s logo, weight and unique serial number. Be cautious, though, as fake gold can also be stamped with fake hallmarks.
So, the next time you need to spot fake gold, remember these six methods and take the guesswork out of your gold testing.
