No — silver does not attract a magnet. Silver is a diamagnetic metal, so neither pure silver nor 925 silver will stick to a magnet; however, a lack of reaction does not prove that you are holding silver, because silver-plated brass will behave exactly the same way.
The magnet test is popular because it costs nothing and takes a second. The problem is that it only determines one thing — and not the one the buyer cares about. Below: what it really tells you, when it is misleading, and what to check instead.
Does silver attract a magnet? The short answer
Silver is a diamagnetic metal. This is not “weak attraction” but the absence of attraction — or, strictly speaking, slight repulsion, so slight that it can only be detected by measuring equipment. A magnet placed on a silver sheet simply rests on it — nothing pulls it toward the sheet.
This applies equally to pure silver and to the 925 alloy used to make jewelry. The additive — most often copper — changes nothing here, because copper is not attracted to a magnet either. So if someone assures you that “real silver is slightly attracted,” they are simply mistaken.
What happens when the magnet does stick
A clear attraction indicates the presence of a ferromagnetic material: iron, ordinary steel, nickel, or cobalt. A solid, homogeneous piece of silver will not behave this way, so strong attraction is a signal you should not ignore.
This is the only situation in which the test is useful — and it is a negative signal. A magnet can tell you, “There is something here that should not be in silver.” It will never tell you, “This is silver.” Before you put the item aside with a sigh, however, read the section about clasps: that is where the most common false alarm comes from.
How it works for us
Since a magnet proves nothing conclusively, and the starting point is the hallmark and description, we show what the material looks like when stated explicitly on the product page. The simplest example from our catalog is Silver Chain — PLN 89 for 45 cm, PLN 129 for 60 cm, PLN 179 for 80 cm. The product description states clearly: Ag925 silver, diamond-cut bead chain, 1.2 mm thick.
The mixed-metal product shown is Rock Crystal and Tourmaline Bracelet — PLN 250; it costs the same in both metal versions. Faceted stones interspersed with silver beads; bead diameter approximately 3 mm, wrist circumference 14 cm plus a 4 cm extender. Choose either 925 silver or 925 silver plated with 24-karat gold. It is also a good example of a piece for which the magnet test is even less reliable than it is for a solid piece. We have gathered necklaces with stones set in silver in a separate collection: necklaces with stones in silver.

Why the lack of attraction proves nothing
This is the most important sentence in the entire text: a magnet also does not attract brass, copper, aluminum, zinc, tin, or lead. Silver-plated brass will pass the “magnet test” just as smoothly as 925 silver—and from the outside, it looks exactly the way silver should look.
| Reaction to a magnet | Metals |
|---|---|
| Clearly attracted | iron, nickel, cobalt, most steels (ferritic and martensitic) |
| No noticeable reaction | silver, copper, brass, alpaca (nickel silver), aluminum, zinc, tin, lead |
Look at the bottom row—it lists metals that a magnet cannot distinguish from silver. This entire group passes the test, so the statement “the magnet does not pull it, therefore it is silver” is an unwarranted conclusion.
One item on this list is worth examining more closely. Alpaca, also called nickel silver or argentan, is an alloy of copper, nickel, and zinc—despite its name, it contains not a gram of silver. It looks like silver, is cheaper, and usually does not react to a magnet, even though it contains nickel. Nickel itself is ferromagnetic, but when bonded in this alloy, it no longer behaves that way—that is why alpaca passes the magnet test just as smoothly as 925 silver. It is one of the most common materials mistaken for silver.
Clasp and spring—the most common false alarm
In many genuine silver pieces, the magnet reacts to a small component rather than the entire piece. The spring in a lobster clasp, the clasp’s core, or another springy component may be made of steel in the industry—silver is simply too soft for these tasks.
The result is that a magnet may “catch” a chain in exactly one place: at the clasp. This does not determine the material of the entire piece. If you do test it, place the magnet in several spots and check whether the whole piece reacts or just the one centimeter next to the clasp.
A separate case, and at the same time the strongest false alarm you may encounter: magnetic clasps. They are sometimes used in bracelets and necklaces because they make one-handed fastening easier—and contain a genuine permanent magnet. Such a clasp will not only react to a magnet, but will actually attract or repel it, depending on which side you bring it close to. This behavior is much stronger than with a steel spring and can easily be mistaken for proof that the entire piece is made of “some kind of metal.” If your jewelry fastens magnetically, a magnet test simply will not tell you anything about it—you need to test the rest of the piece away from the clasp.
A reaction at the clasp alone is therefore not a reason to return the package—it is a reason to check the rest. Move the magnet along the entire chain, bring it close to the pendant, and place it against a smooth surface away from the fittings. And if nothing happens there, you know less than you might think: these areas do not contain a strongly magnetic metal. Not all steel reacts to a magnet—austenitic grades, also found in small jewelry components, can be practically nonmagnetic. You still know nothing about the material; to answer that question, you need to check the hallmark and the description.
The Sliding Neodymium Magnet Test—Better, but Still Only a Clue
There is a cleverer method than simply holding a magnet against it. When a strong neodymium magnet is released down an inclined, thick, flat silver surface, it slows noticeably instead of sliding down as it would on glass. This is caused by eddy currents (Foucault currents), which the moving magnet induces in a good conductor—their field opposes the motion that created them, in accordance with Lenz’s law.
The effect is attractive and genuinely shows that there is a metal underneath that conducts electricity well. However, it has specific limitations:
- You need a substantial, solid piece. You will not see anything on a 1.2 mm-thick chain or on bracelet beads.
- Copper, brass, and aluminum also slow down a magnet because they conduct electricity as well—and in a silver-plated item, the result is determined by the core, not the thin coating.
In other words, this test tells you that you have a good conductor—it does not tell you which one. It is a stronger clue than holding up a magnet, but it is still only a clue.
How to Identify Genuine Silver: The 925 Mark and a Trusted Source
The marking on the item tells you much more than a magnet does. Look for the hallmark in four places: inside the ring, on the clasp of a necklace or bracelet, on the tag next to the lobster clasp, and on the earring post.
With one important caveat: a hallmark alone is neither necessary nor sufficient—small items may be exempt from hallmarking requirements, and hallmarks can be forged. We explore this issue in a separate article about what 925 silver means. The second cornerstone is the source of purchase: a seller who states the material clearly in the description and takes responsibility for it.
The most authoritative test is performed at an assay office. A professional test by a jeweler—acid-based or XRF—provides a strong indication, but it has its limitations: XRF primarily reads the near-surface layer, so a sufficiently thick coating can mislead it. To be clear: at a jeweler’s, not in your kitchen. Home tests involving acid, scratching with a blade, or heating damage the item and still do not provide a reliable result. The same principle applies to minerals— we discussed their verification in our guide on how to identify a genuine stone.
FAQ — Magnet and Silver
Does a neodymium magnet attract silver?
No. Neodymium magnets are the strongest commonly available magnets, but their strength does not change the nature of the metal: silver remains diamagnetic and will not be attracted. Such a magnet is useful for another test, however—when released on an inclined, thick silver surface, it clearly slows down because of eddy currents.
Does a magnet attract 925 silver?
No. 925 fineness means an alloy composed of 92.5% silver, with the remainder usually being copper—neither of these metals is attracted to a magnet. If silver jewelry reacts, look for a small steel component in the clasp or a completely different metal beneath the coating.
How else can you test silver at home?
Home methods are indicative only and should be treated that way: examine the item under a magnifying glass for a 925 hallmark, check whether the coating is wearing off at the edges, and—for a thick, flat item—perform the sliding magnet test. We advise against acid, scratching with a blade, and heating: they damage the item without settling the matter. Certainty comes from testing at an assay office; a professional jeweler's test is a strong indication, although even XRF can be misled by a thick coating.
What does it mean when jewelry is attracted to a magnet?
That it contains a ferromagnetic material—iron, ordinary steel, nickel, or cobalt. Before you decide that the item is a fake, check exactly where the magnet sticks: a reaction limited to the clasp itself can be normal, because clasp springs and cores are often made of steel. An earring post is different: in an item sold as 925 silver, the post should be silver, so a magnet reacting specifically to it is a warning sign, not a minor detail. Attraction across the entire surface is a completely different signal: there is a substantial magnetic element inside. A solid piece of typical silver will not behave this way—but this alone still does not tell you how much silver the item contains or where it is.
Does darkening mean that it is not silver?
No. 925 silver darkens because it reacts with sulfur compounds present in the air and cosmetics—this is a natural phenomenon, not evidence of a fake. We have collected ways to restore its shine in a separate guide: how to clean silver.
To sum up: a magnet is a rough screening tool and is useful only in that role. It can tell you “there is steel here,” but it cannot tell you “this is silver.” If you want to know what you have on your wrist, start with the hallmark and product description, and for a more expensive purchase—with a seller who can substantiate both.
