Sterling Silver vs Silver Plated — What's the Difference?

If you're shopping for silver jewellery online, you've probably noticed that some pieces are described as "sterling silver" and others as "silver plated" — and the price difference can be massive. But what's the actual difference, and why does it matter?

The short answer: sterling silver is the real thing, all the way through. Silver plated is a thin coating of silver over a cheaper base metal. One lasts a lifetime. The other doesn't.

What Is Sterling Silver?

Sterling silver is an alloy made from 92.5% pure silver and 7.5% other metals, usually copper. The copper is added because pure silver on its own is too soft for everyday jewellery — it would bend and scratch too easily. That 92.5% standard is why you'll often see sterling silver referred to as "925 silver" or stamped with a "925" hallmark.

When you buy a sterling silver ring, necklace, or pair of earrings, the silver runs through the entire piece. There's no coating to wear off. The piece is silver, inside and out.

What Is Silver Plated?

Silver plated jewellery starts with a base metal — usually brass, copper, or zinc alloy — and then gets a very thin layer of silver applied to the outside. That silver layer is typically just a few microns thick. For context, a human hair is about 70 microns.

This is why silver plated jewellery is cheaper. You're getting a tiny amount of actual silver on the surface of a much less expensive metal underneath.

Why Does It Matter?

Durability. Sterling silver can last for decades — even generations — with basic care. Silver plated jewellery will eventually wear through, revealing the base metal underneath. That's when you start seeing discolouration, green marks on skin, or a brassy look. Most silver plated pieces start showing wear within a year or two of regular use.

Skin reactions. Because silver plated jewellery exposes the base metal once the coating wears, people with sensitive skin often react to it. Sterling silver is nickel-free (at Belle Jewellery, all our pieces are certified nickel-free), making it far less likely to cause irritation.

Value. Sterling silver holds real material value. Silver plated jewellery has almost no resale or scrap value because there's so little actual silver in it.

Appearance. Both look the same when brand new. But sterling silver develops a natural patina over time that many people love — and it cleans up beautifully with a polishing cloth. Silver plated pieces can't be polished in the same way without risking damage to the thin coating.

How to Tell the Difference

Look for a 925 stamp on the piece. This is the international hallmark for sterling silver. If a piece doesn't have this stamp, it's likely plated. Be cautious of terms like "silver tone", "silver finish", or "silver colour" — these almost always mean plated or not real silver at all.

At Belle Jewellery, every piece in our sterling silver collection is solid 925 sterling silver, stamped and verified. We never sell silver plated jewellery. That's a deliberate choice — we'd rather sell fewer pieces that last than more pieces that don't.

Is Sterling Silver Worth the Extra Cost?

If you're buying a piece you want to wear regularly, yes. The cost difference between a sterling silver ring and a silver plated one might be €20–€40, but the sterling silver piece will still look good in five years. The plated one probably won't make it past two.

For gifts, the same logic applies. A sterling silver Claddagh ring or necklace is something someone can keep and wear for years. A plated version might look the same in the photo, but the recipient will notice the difference soon enough.
