Silver turns up in places that don't come with paperwork: a box of cutlery from an estate sale, a chain inherited from an aunt, a handful of coins in a drawer. The colour looks right and the weight feels right, but you want to know before you polish it, sell it, or hand it to someone else. A few household tests can rule out the most obvious fakes in under a minute. What they cannot do is tell you, on their own, whether a piece is sterling, coin silver, or a very convincing plate.
What follows is an honest ranking of the home tests — which ones are safe, which ones are mostly theatre, and which ones quietly cost you money. The short version: test gently, test in more than one way, and stop before you scratch something you might later sell.
Read the Marks Before You Test Anything
Start with a loupe or your phone's magnifier, not a magnet. Look on the back of spoon and fork handles, the inside of ring bands, the clasp of a chain, and along the rim of a tray. Marks are small and often worn half away, so angle the piece under a lamp and be patient.
- 925, STERLING or a lion passant: sterling silver, nominally 92.5% pure.
- 999 or FINE SILVER: near-pure silver, soft and usually reserved for bullion and some jewellery.
- COIN or 900: older 90% silver, common on antique flatware and coins.
- EPNS, EP, SILVER PLATE, GERMAN SILVER, NICKEL SILVER: none of these are solid silver, whatever the colour suggests.
An absent mark proves nothing. Marks rub off, and plenty of older pieces from outside Europe were never stamped at all. A present mark proves less than people assume, too — stamping a plated item "925" is an old trick. Treat hallmarks as evidence, not a verdict.
The Magnet Test: Fast, Free, and Often Misread
Silver is not magnetic. A strong neodymium magnet — the small disc kind that comes with fridge accessories — will not grab a silver spoon or chain. That makes the test useful for catching one specific fake: steel and nickel-alloy items dressed up to look like silver. Nickel is magnetic, and so is the steel core inside plenty of cheap plated jewellery.
Here is how to run it properly:
- Hold the magnet close to the item and let go. Don't press it against a polished surface.
- Watch for a hard pull. A firm attraction means you are holding steel or a nickel alloy, not silver.
- Ignore a faint drag. Silver is weakly repelled by a magnet rather than attracted, and a strong magnet can still feel a slight tug against a large, curved piece.
The catch is that copper, brass, pewter, aluminium, zinc and stainless steel are all non-magnetic. A fake that passes the magnet test has told you almost nothing. Use it as a screen, not a conclusion.
Ice, Sound, and the Feel of Real Silver
Silver conducts heat unusually well, which is the basis of the ice test. Put the piece on a dry cloth at room temperature, rest an ice cube on it, and watch. On solid silver the ice tends to melt and slip quickly, and condensation beads up almost immediately. It is a pleasant five-second check, but aluminium conducts heat well too, and a thin plated spoon will pass just as happily. Enjoy it as a hint.
The ring test is more useful if you practise first. Balance a silver ring or coin on a fingertip and tap it lightly with another coin. Genuine silver gives a clear, high, sustained tone that hangs in the air for a second or two. Plated base metal and pot metal thud and stop dead. Thin chains barely ring at all, so don't write off a good necklace because it sounds flat; heavy cast pieces and coins are the fair test. Do this over a soft surface, and tap gently — you are listening, not striking.
Then there is feel. Silver is dense for its size and warms quickly in the hand. Experience is the only way to learn this, so handle every piece of known silver you can: a friend's christening spoon, a grandparent's serving dish, a bullion coin. Your palm remembers longer than your notes do.
The Soft Cloth Test, and What Smell Can Tell You
Take a clean white cotton cloth and rub gently on an inconspicuous spot — the back of a handle, the inside of a bangle. Real silver that has been sitting around leaves a grey-black smudge of tarnish on the cloth. Plated items tend to leave a lighter, more yellowish or brownish residue as the plating wears, and solid copper or brass leave their own colours.
Two warnings. Never scrub, and never reach for toothpaste, bicarbonate of soda or a kitchen scourer: these are abrasives and they will dull a finish or wear through plating in seconds. A jeweller's polishing cloth is the right tool. Second, don't rub a coin or an antique with any remaining patina — that dark recess shading is part of its value, and cleaning it can halve what a collector will pay.
Smell is a rough companion test. Warm a piece in your hands and sniff. Silver has a faint, cool, metallic smell. Brass and copper leave a distinctly penny-like scent on your skin. It is not proof of anything, but it is one more small clue.
Skip the Harsh Stuff: Acid, Bleach and Scratch Tests
Search around and you will find instructions involving household bleach, nitric acid testing kits, and filing a groove into the metal. Be sceptical.
Bleach will not give you a reliable answer, and it can stain or damage a finish you cannot restore. Acid testing solutions sold online do work in trained hands, but they are corrosive, they need ventilation and gloves, they leave a permanent mark where they are applied, and they are easy to misread on plated items. Filing exposes the metal underneath, which is exactly the point — and exactly why you should not do it to anything you might sell, insure or pass on. A file mark on an antique is money off the price.
Treat these as bench methods, not kitchen-table methods. If you feel you need acid to settle the question, you already need a professional.
The Density Check: Accurate but Fussy
If you own a jeweller's scale that reads to 0.01 g, you can measure density. Weigh the piece dry, then weigh it suspended in water by a thin thread, and work out the ratio. Silver sits around 10.5 g/cm³, copper around 8.9, zinc around 7.1, lead around 11.3. The numbers are far enough apart to be meaningful.
The fussiness is the problem. Air bubbles cling, hollow handles and chains trap air, and a small weighing error throws the result off. Do it as a cross-check when the magnet and cloth tests have left you unsure, and expect to repeat it two or three times before trusting a figure.
When Paying a Jeweler Is Worth It
A bench test at a jeweller is usually quick and often inexpensive, and there are clear situations where it is the sensible choice rather than an extravagance: a piece you intend to sell or insure, an inherited set you cannot identify, a hallmark in a script you don't recognise, or any item where the value comfortably exceeds the cost of finding out. Ask specifically for an X-ray fluorescence reading, often shortened to XRF. It is non-destructive, it reads the metal's composition in seconds, and it tells you the actual percentage of silver rather than a yes-or-no answer. Not every workshop has one, so phone ahead.
Also ask what you are getting. A verbal "that looks like silver" from a shop assistant is not the same as a written reading with the percentage noted. For anything you plan to sell on or insure, get the figure in writing and keep it with the piece. If money is genuinely at stake — a large flatware service, a box of coins, a family piece you are thinking of parting with — a paid appraisal from a qualified valuer is worth more than any number of home tests, and worth asking about directly.
A Five-Minute Routine Before You Decide
Work through the same short sequence every time, cheapest and least invasive first, and write down what you find.
- Look for marks with a loupe, and photograph them.
- Run a strong magnet over the piece and note any hard pull.
- Rub a hidden spot with a soft white cloth and check the colour of the smudge.
- Tap a heavy, solid piece and listen to the tone.
- Weigh it, if you have a scale, and record the figure in grams.
If the marks, the cloth and the sound agree, you can be reasonably confident — and reasonably cautious. If they disagree, or if the item matters financially, stop testing and book a jeweller. Never clean a suspect piece aggressively before it has been assessed, keep any receipts, boxes or notes that came with it, and remember that the most expensive mistake in this hobby is not a fake spoon. It's a real one that someone polished the patina off.
