Sterling silver has been used for centuries in everything from flatware to fine jewelry. But with so many look-alikes and plated alternatives on the market, identifying authentic sterling silver isn’t always straightforward.
Whether you're holding a tarnished spoon from an estate sale or inherited a set of candleholders, knowing how to determine what’s real—and what’s not—can save you time, money, and potential disappointment. Here’s a complete guide to recognizing genuine sterling silver.
The fastest way to check for authenticity is to look for a marking, often found on the underside or inside of a piece. For sterling silver, the most common stamps include:
These indicate that the item is made of 92.5% pure silver, the standard for sterling. However, be cautious: fake markings do exist, especially on imported goods or pieces made to deceive. Don’t rely on markings alone without further testing.
Sterling silver has a distinct feel. It's heavier than aluminum or stainless steel but lighter than lead or pewter. While this isn’t foolproof, comparing a known sterling item with an unknown one can be revealing.
Tapping the silver gently can also produce a recognizable sound. Real sterling often gives off a high-pitched ring when lightly struck, especially in items like goblets or serving trays. Fake or plated metals tend to sound dull or muted.
Contrary to popular belief, tarnish can be a good sign. Sterling silver naturally darkens over time due to exposure to air and moisture. A light patina suggests age and authenticity.
However, excessive flaking or greenish discoloration may indicate base metals beneath a thin silver plating, not solid sterling. In these cases, polishing a small, inconspicuous area can help. If the piece remains silver underneath, that’s a good sign. If a different metal begins to show through, it’s likely not sterling.
One of the easiest at-home checks is a simple magnet. Silver is not magnetic. If a magnet sticks strongly to your item, it’s almost certainly not real sterling silver.
That said, some non-silver metals are also non-magnetic, so this test alone doesn’t confirm authenticity—but it can help rule out obvious fakes.
For those who need a more definitive answer, silver testing kits are available that use nitric acid to verify content. A small scratch is made in an inconspicuous spot, and a drop of acid is applied. Real sterling silver typically turns a creamy color when the acid reacts.
Because this method can damage the surface, it should only be used when absolutely necessary—and ideally by someone familiar with the process.
Different countries use different standards and symbols. British silver may include a lion passant, while French silver often features the Minerva head. These traditional hallmarks can reveal not just authenticity but also origin, maker, and date of manufacture.
Learning to identify international marks can be especially helpful when dealing with antique or imported pieces. Many guides and databases exist to help decipher obscure symbols.
Silver-plated objects are the most common source of confusion. These items are typically made of base metals like brass or copper and coated in a thin layer of silver. Over time, the plating can wear off—especially around edges and handles—revealing the underlying material.
Common plated markings include:
None of these indicate real sterling silver, and their value is often decorative rather than intrinsic.
Knowing how to tell if you have real sterling silver takes a combination of observation, testing, and familiarity with common hallmarks. While some pieces are clearly marked and easy to verify, others require a more hands-on approach. With the right tools and knowledge, anyone can become more confident in identifying authentic silver items—whether they're family heirlooms or unexpected treasures.
