What “925 sterling silver” actually means

If you’ve ever spotted “925” on a jewelry listing and wondered what it means, we’re glad you asked. Sterling silver is real silver mixed with a small amount of other metals. The number means 92.5 percent silver, with the remaining 7.5 percent made up of other metal, commonly copper. That mixture is an alloy. Pure silver is relatively soft, so alloying helps make it more practical for pieces you wear and handle.

One distinction we want you to feel comfortable with is sterling versus silver-plated. In a sterling component, the underlying metal is the silver alloy. In a silver-plated component, a thin layer of silver covers another metal. “Silver-colored” only describes the look. It doesn’t tell you which construction you’re buying, so it’s worth asking for the material rather than relying on the photograph.

There can be another layer to the story, too. Sterling jewelry may have a finish such as rhodium plating or deliberately darkened details. Knowing the metal underneath doesn’t automatically tell you how to polish the finished piece. We also encourage you to ask about the chain, connectors and charms individually. A design with several elements doesn’t necessarily use one material throughout.

And yes, genuine silver can tarnish. Reactions at its surface can change its color, so darkening alone doesn’t mean a piece is fake. A bright finish alone doesn’t prove that it’s sterling, either. Keep the material description and care information from your purchase; those specifics are much more useful than trying to judge everything by shine.

When you’re choosing jewelry, ask what the base material is, whether it has a coating, and how to care for that exact design. If particular metals bother your skin, ask about the alloy and each component rather than treating “hypoallergenic” as a guarantee. We’d love to help you explore the options at Starmarked.
