Sterling silver has long been a benchmark of quality in jewelry, tableware, and decorative arts. But with so many silver-plated and mixed-metal items in circulation, it’s not always easy to tell whether a piece is truly sterling or just looks the part. So how do you know if what you’re holding is actually sterling silver?
Fortunately, there are several reliable ways to determine whether a silver item meets the sterling standard — some you can do at home, and others may require professional confirmation.
The first step in identifying sterling silver is to check for hallmarks or stamps. On most legitimate sterling items, you’ll find one or more of the following:
Hallmarks are typically located on the underside or hidden edge of a piece — on the back of a spoon, inside a ring band, or along the base of a tray.
Keep in mind that absence of a mark doesn’t necessarily mean the item isn’t sterling — especially for older or worn pieces — but it does mean further testing is warranted.
Silver-plated items often reveal a different base metal underneath when scratched, nicked, or heavily used. In contrast, genuine sterling silver is solid through and through. Examine areas of natural wear closely: if you see a brass or copper tone beneath the surface, it’s likely plated.
This method isn’t foolproof, especially if the item is in excellent condition or has been polished regularly, but it can offer quick clues.
Sterling silver tends to have a noticeable heft compared to plated alternatives, which often feel lighter due to a different core material. Likewise, if gently tapped, sterling often gives off a soft, resonant “ring,” while plated or base metal items produce a duller sound.
These are more subtle tests and best used in combination with other evidence — especially if you're handling multiple types of metals regularly.
Silver is not magnetic. If a strong magnet sticks to your item, it’s not sterling. However, many base metals used in plated silver are also non-magnetic, so this test can only rule out, not confirm, authenticity.
It’s a helpful step, but shouldn’t be relied on alone.
For a more definitive answer, especially if you’re unsure after examining markings and wear, silver testing kits are available. These use an acid solution that reacts to the metal and changes color based on its composition.
Apply the solution to a discreet area or testing stone — a specific color change will confirm whether the item is sterling. If you’re unsure how to interpret the result, a local jeweler or metals specialist can help.
Be aware that testing solutions are acidic and can cause damage if misused, so care should be taken when performing this test.
If you're dealing with a valuable, antique, or unmarked item, a professional evaluation is often the best course. Experts can determine silver content through a combination of visual inspection, experience with hallmarks, and advanced tools like X-ray fluorescence testing.
This route is especially recommended if you're planning to sell or insure the item.
Determining whether a piece is sterling silver involves a mix of observation, common-sense testing, and sometimes expert help. The most reliable indicators are hallmarks, consistent metal color, and wear patterns — but no single method is definitive on its own.
If the piece is marked “925” or “Sterling” and passes a few of the other simple tests, there’s a good chance it’s genuine. When in doubt, verification through a reputable appraiser will give you peace of mind.
