Sterling silver is prized for its brilliance and value, making it a popular choice for jewelry, flatware, vases, and more. Its beauty and market worth set it apart from silver-plated or imitation items, which often lack the same luster and longevity. Beyond aesthetics and cost, identifying real silver is also crucial for individuals with metal allergies, as wearing non-silver metals can cause adverse reactions.

If you’re shopping for second-hand silver, you can find incredible deals—if you know what to look for. Silver, like other precious metals, has distinct characteristics that can help determine its authenticity. According to antique experts, these simple tests can help you identify whether an item is made of genuine silver.

The Magnet Test

One of the easiest ways to check if an item is real silver is with a magnet. Precious metals such as gold and silver are non-magnetic. If your item is strongly attracted to a magnet, it is not pure silver.

“Silver is not noticeably magnetic and exhibits only weak magnetic effects, unlike iron, nickel, or cobalt,” explains Nicolas Martin, flea market expert and founder of Flea Market Insiders. “If a magnet sticks strongly to the piece, it likely has a ferromagnetic core and is not silver.” Many silver-plated or imitation silver pieces are made from other metals, making this a quick and reliable test.

The Hallmark Test

Authentic silver items typically bear specific markings that indicate their purity.

“The first thing you should check for is a stamp or hallmark,” says Martin. “A silver object sold commercially is usually stamped with one or more hallmarks denoting its purity, the maker’s mark, and sometimes a date of manufacture.”

Internationally recognized silver purity marks include 925, 900, or 800, indicating the percentage of silver content. Sterling silver is 92.5% pure silver, often marked as 925. If an item lacks a stamp, it may not be genuine silver or may require further testing.

The Odor Test

Sterling silver is odorless. If you notice a distinct metallic or sulfur-like smell, the item is likely not pure silver.

Fake or silver-plated items often contain base metals that produce an odor. If your piece has an unpleasant metallic scent, it is worth testing further.

The Polish Test

Real silver tarnishes over time due to oxidation, forming a black or dark grey residue.

“After checking for stamps and using the magnet test, try polishing the item with a soft white cloth,” advises antique expert Sue Whitney. “If it’s genuine silver, a black residue will appear on the cloth.”

If no tarnish comes off, or if the item appears to rust rather than oxidize, it is likely made of another metal.

The Flake Test

Some items are silver-plated rather than solid silver, meaning they have only a thin layer of real silver over another metal.

To check, gently scratch an inconspicuous area or look for signs of flaking. If another metal appears beneath the surface, the item is only silver-plated. A more advanced test involves placing silver flakes into acid—pure silver will not change the acid’s color, while other metals might.

The Ice Test

Silver is the most thermally conductive common metal, which means it can transfer heat very quickly.

To test this, place a cube of ice on the silver item and observe how quickly it melts. “Even at room temperature, authentic silver will melt ice rapidly,” says Martin. “If the ice melts unusually fast, the item is likely silver.”

Identifying real silver can be simple if you know what to look for. By using these expert-approved tests, you can confidently determine whether an item is made of genuine silver or just an imitation.
