Can a Magnet Test Tell If Gold Jewellery Is Real? A Singapore Guide

A magnet is an easy object to reach for when you want to check gold jewellery at home. But the result is often misunderstood. A chain that is attracted to a magnet deserves a closer look; a chain that is not attracted has not been proved genuine. For a Singapore buyer comparing 916 or 999 gold jewellery, the useful question is not “Did it pass the magnet test?” but “What does the seller say the piece is made of, and how can that claim be checked?”

What a magnet can—and cannot—show

Pure gold is not strongly attracted to an ordinary magnet. That makes a strong response from the main body of an item a reason to ask questions. It does not identify the metal, tell you the gold content or establish that the entire item is fake. A piece may combine different materials, and a small component can behave differently from the visible gold-coloured section.

The reverse conclusion is even more important: no attraction does not prove that an item is 916, 999 or even solid gold. Many non-gold materials are not strongly attracted to a household magnet. Gold-coloured plating over a non-magnetic base can also look convincing. A simple pass-or-fail rule therefore gives buyers false confidence.

Why the clasp can confuse the result

Consider how a necklace is built. A chain, jump ring and spring clasp are separate parts. A magnetic response concentrated at a clasp tells you something about that small area, not necessarily about the chain links. Conversely, a non-magnetic clasp does not certify the links. If you notice an unexpected response, note exactly where it occurs and ask the seller to explain the construction of that particular item.

Do not pull hard on a clasp or drag a magnet over delicate settings in an attempt to make the result more obvious. That can scratch a finish or strain a fine chain. Home checks should not damage the jewellery you are trying to assess.

Read the stated gold specification first

Before purchase, look for a clear description of the metal. “Gold colour” describes appearance. “Gold plated” describes a coating. A stated fineness such as 916 or 999 is a different claim about gold content. These phrases are not interchangeable. The US Federal Trade Commission’s jewellery buying guide explains why buyers should distinguish gold jewellery from plated and filled items. Its terminology is helpful for comparison, although it is not a substitute for Singapore-specific product information.

Ask whether the stated fineness applies to the whole item or only to a component. For a piece with a stone, enamel, cord or other non-gold part, ask how its total weight is described. For a chain, ask about the chain and fastening separately if the listing is unclear. Keep the written product description and receipt so you can compare what you received with what was represented.

Use marks as information, not a complete verdict

A fineness mark can be a useful clue, but a stamped number alone cannot tell you that every part of a piece has the stated composition. Marks can be absent on very small components, hard to read, or misrepresented. Look at the wording of the listing and the seller’s documentation together, rather than treating one close-up photograph as final proof.

If a claim matters to your decision, ask the seller what verification supports it and whether a qualified professional can assess the actual piece. The Gemological Institute of America describes a touchstone method for assessing karat gold, but that is a bench procedure involving chemicals and judgement, not a kitchen-table test to copy at home. Some professional methods examine a surface and may require further interpretation. Ask what a test does and does not establish before relying on its result.

A practical Singapore buying checklist

Before paying

Read the exact metal description, fineness claim and item weight. Check whether the listing describes a solid, hollow, filled or plated construction, and whether any stones or non-gold elements are included. Compare the product photographs with the written description; colour alone is not a reliable measure of purity. If the clasp, links or setting are important to you, ask for close-up images or inspect the item in person where possible.

When receiving the piece

Check the item against its order record: design, quantity, size, stated material and any visible marks. Inspect the clasp and joins for condition, rather than trying to prove purity with a magnet. Keep the receipt and relevant product information together. If something does not match, contact the seller with the specific discrepancy and photographs before altering or testing the item.

When uncertainty remains

Ask for clarification in writing. If the item is valuable to you or a material claim remains disputed, consider an independent, qualified assessment. Explain which part of the jewellery you want assessed and what question you need answered. An assessment of one accessible area should not automatically be treated as a complete analysis of a multi-part piece.

Frequently asked questions

Does a non-magnetic result mean my chain is real gold?

No. It only means the area checked did not show a strong response to that magnet under those conditions. It does not establish fineness, solid construction or authenticity.

If only the clasp attracts a magnet, is the chain fake?

Not necessarily. The clasp and chain may have different components. Ask the seller for a clear explanation of the entire item, including any fastening materials, and seek professional advice if the answer affects your decision.

Can a magnet distinguish 916 from 999 gold?

No. A household magnet cannot measure gold fineness. Compare the written specification and supporting records, and use a suitable professional assessment when independent verification is needed.

Should I try acid or scratch tests at home?

Those tests can damage jewellery and involve hazardous materials. Leave them to a qualified professional who can explain the method, limitations and possible effect on the piece.

Make the claim—not the magnet—the starting point

A magnet may raise a useful question, but it is not an authenticity certificate. For gold jewellery in Singapore, a better buying routine is to identify the exact material claim, check the whole item’s description and documentation, and ask how any important uncertainty can be resolved.
