Tarnish or Plating Wear? How to Tell the Difference
Share
Two different things can make silver-colored jewelry look worse over time, and they need opposite fixes. Confuse them and you'll either throw away a piece that just needed cleaning, or keep polishing something that's never coming back.
Here's how to tell which one you're looking at.
The one-sentence version
Tarnish sits on top of solid metal and comes off. Plating wear is the loss of a thin metal layer, and it doesn't come back.
One is maintenance. The other is a countdown that already ran out.
Tarnish, in detail
Tarnish is a chemical reaction — the metal reacting with sulfur compounds in the air. It forms a dark film on the surface of solid metal. The metal itself hasn't changed; it's just wearing a layer of discoloration.
What tarnish looks like:
- Darkens gradually, usually over months
- Starts in the recesses and low points first — that's where air sits still longest
- Fairly even in tone across the darkened areas
- Comes off with cleaning and doesn't come back quickly
- Underneath the tarnish, the metal color is the same everywhere
Plating wear, in detail
Plating is a thin layer of one metal — often a silver-colored or silver-toned finish — applied over a different base metal underneath. It's a completely legitimate, widely used construction method, and there's nothing wrong with a plated piece being what it is. The issue only comes up when a piece wears through and it isn't clear what's actually happening.
What plating wear looks like:
- Shows up specifically at high points and contact areas — the places that rub against skin, clothing, or other jewelry. A ring's band, an earring post, the inside curve of a bracelet.
- The color underneath is usually visibly different — yellow, pink, grey, or brassy, depending on the base metal
- The transition is often abrupt rather than gradual — you can frequently see a distinct edge where the plating stops
- No amount of cleaning brings the original color back, because there's no original color left in that spot — the layer that had it is gone
The test that actually works: location
This is the single most useful thing to check, and it takes ten seconds.
Look at where the discoloration or color change is happening.
- In the recesses, the carved details, the low points, the parts that don't touch anything? That pattern is tarnish. Clean it.
- On the high points, the edges, the places that constantly rub against something? That pattern is wear — and if a different color is showing through, that's plating wearing off.
Tarnish and wear follow opposite geography. Tarnish collects where air sits still. Wear happens where friction is constant. A piece can have both at once, in different spots, and that's normal — check each area on its own terms rather than assuming the whole piece is one or the other.
The test that helps, but isn't proof: color underneath
If you can see a different-colored metal in a worn spot — yellow-gold, pink-copper, a dull grey — that's a strong sign of plating wear, because solid silver doesn't have a different color hiding under its surface. There's nothing underneath a solid piece except more of the same metal.
I say "strong sign" and not "proof" on purpose. From a photo, color can be affected by lighting, by the angle, by what's oxidized nearby. It's a good clue. It isn't a verdict on its own.
Why we plate, and what we plate for
Rhodium plating has a mixed reputation in this trade, and some of it is earned. A bright white layer can be used to cover porous metal and rough casting — the plating carries the finish the work underneath never got, until it wears.
That is not why it is on our pieces. Joryel began plating because he was tired of polishing his own silver. A micron of rhodium gives sterling a tarnish-resistant finish with the tone of white gold. Like any finish it wears at the points that rub — and on our pieces what shows through is sterling, because the metal is sterling all the way through: a slightly warmer, softer white, not yellow and not pink. Rhodium costs more than platinum now; it is on our work for what it does, not for what it hides.
Which is also why the location test above is worth trusting on our pieces: what is underneath is finished before the plating goes on.
What each one means for what you do next
If it's tarnish: clean it. I wrote up the method here — a soft cloth handles most of it, and it costs nothing.
If it's plating wear: cleaning won't bring it back, because there's nothing left in that spot to bring back. The honest options are wearing it as-is with the wear visible, having it replated (which is possible, though the wear will eventually return to the same high-friction spots), or retiring it. None of those is a defect on your part or a scam on anyone's — plating is disclosed for what it is when it's sold correctly, and it simply has a different lifespan than solid metal by design.
If you're genuinely not sure
Some pieces are ambiguous even in person, and a photo makes it harder, not easier. If you've checked the location and the color and you're still not sure what you're looking at, that's a completely normal place to land — this isn't always obvious, even up close.
Send me a couple of photos — the whole piece and a close-up of the worn area — and I'll tell you honestly what I'm seeing. I can't confirm metal content from a photograph; nobody can. But I can tell you which pattern it looks like, and that's usually enough to know what to do next.

This is general information to help you tell two common patterns apart. It isn't a determination about any specific piece, and photographs have real limits — testing in person is the only way to know for certain.
