As experts in the world of gold buying, we have encountered numerous pieces of fake gold jewellery. This is not referring to gold plated jewellery, but jewellery that may be hallmarked as 14ct solid gold and is actually plated or of a much lower gold purity. We have some of the best gold testing equipment in the business, such as an XRF scanner which can provide us with really clear results up to a certain scan depth. However, without access to this equipment there are some simple ways you can check if your gold is real from home. These tests cannot provide a 100% definitive conclusion, but can give you a strong signal. We always recommend using a professional gold testing service when possible.
Here’s a step-by-step guide to help you identify fake gold jewellery and plated gold jewellery from home.
Step 1: Check for Hallmarks
Hallmarks are the first step and quickest way to verify gold authenticity. Most genuine gold jewellery will have small stamps indicating its purity. In the UK it is the law for all gold jewellery sold to be hallmarked. This is a good first indicator and can often help you distinguish between plated and solid gold, as plated jewellery often features no hallmarks. Common hallmarks you will see in the UK are:
- 9ct, 14ct, 18ct, 22ct – Representing the gold content in carats.
- 375, 585, 750, 916 – Indicating the gold percentage in parts per thousand.
Foreign gold may feature slightly different markings such as 9K, or 9KT. Look for these markings with a magnifying glass or a jeweller’s loupe. These can be very small at times, and can be difficult to see if the jewellery is old or has been worn frequently. Dirt can often accumulate in the hallmarks, so use a toothbrush or other soft-bristled brush to try and clear out any dirt filling the stamp. Be cautious—counterfeiters can add fake hallmarks. If the stamp looks smudged, uneven, or poorly engraved, it’s a red flag.
Step 2: Check For Areas Of Wear
This step is applicable on jewellery that has had a lot of wear. For gold plated jewellery, there can be areas of wear where the base metal is starting to show through. The gold plate layer can often be 0.17 microns to 2.5 microns thick, so areas that make contact with the skin can have the gold plate worn down over time. This can result in a colour difference where the underlying base metal is visible. If you can see areas where this has occurred, it can be a clear signal that the item has a plated layer.
Step 3: Perform the Magnet Test
Gold is not a magnetic material. Using a strong magnet, check your jewellery. If the item is attracted to the magnet, it’s likely made of a base metal like iron or nickel with a gold layer. It’s important to note that solid gold jewellery can often feature areas of internal reinforcement. Metal wire is sometimes found in gold bracelets to give them strength and prevent deforming. Similarly, solid gold necklace and bracelet clasps can have a metal spring which may react to the magnet test.
Keep in mind that some non-magnetic materials, like stainless steel, can also be gold-plated, so this test alone isn’t definitive.
Step 4: Examine the Weight
Gold is denser than most metals. Genuine gold jewellery feels heavy for its size, especially with higher carat jewellery. This can be difficult to establish if you are not used to handling jewellery. You can hold the piece in your hand and compare its weight to a similar-sized item you know is real gold. A lightweight piece could indicate it’s made of hollow gold, gold-plated material, or another alloy.
Step 4: Test with a Ceramic Plate
Gently rub your jewellery on an unglazed ceramic plate or tile. Real gold will leave a yellow or gold streak, while fake gold often leaves a black or grey streak. Be careful not to damage your jewellery with excessive rubbing, as this method can leave scratches.
Step 5: Use the Acid Test
This is a test that requires specialist equipment. An acid test is one of the most reliable DIY methods. You’ll need a gold testing kit, which is readily available online or at jewellery supply stores. Follow these steps:
- Scratch or sand a small area of the jewellery.
- Apply a small drop of acid to a discreet part of the jewellery.
- Observe the reaction. Real gold will remain unaffected, while fake gold or gold-plated pieces may discolour or dissolve.
Always handle acids with care and wear gloves to protect your skin.

Spotting fake gold jewellery at home is easier than you might think, but it’s not foolproof. If you’re still unsure, it’s best to consult a professional gold buyer or jeweller who can test the piece with advanced equipment.
