Why do earrings turn black? Metal reacts with air, moisture, sweat and things like perfume or lotion, and the surface darkens as it does; on plated fashion jewelry, friction can also thin the top layer over time.
Maybe you just took your favorite pair out of the drawer and it looks duller than it did in summer. The good news: a few small habits help day to day, and how to clean earrings walks you through gentle cleaning. This piece is about the why, so you can spot the cause on your own pair.
What is actually happening?
Many metals react with oxygen and with sulfur compounds in the air. That forms a thin, dark film on the surface, which is what people mean by tarnish. With plated jewelry in general, the top layer protects the base metal while it is intact. Where it rubs off over time against hair, collars or your phone, the metal underneath meets the air.
That is why fashion jewelry usually discolors first where it is touched most: the hook, the edges, the back. Hold your pair up to the light and you can often see exactly those spots.
What is causing it on your pair?
Usually two things come together, like the pair that goes in right after the shower and the perfume. The table helps you sort it out.
| Cause | How you notice it | What helps |
|---|---|---|
| Moisture, the bathroom | Dull patches when the pair often sits in the bathroom | Store dry, ideally outside the bathroom. |
| Water: shower, pool, sea | The shine looks flatter | Take them off first and put them back on after. |
| Perfume, lotion, hairspray | A haze or spots, often on the front | Perfume and hairspray first, jewelry second. |
| Sweat and sport | Darker spots on the hook or post | Take them off before a workout and wipe with a soft cloth after. |
| Friction | Uneven spots on edges and the back | Store pieces separately and take them out at night. |
| Left out in the open | The whole piece looks evenly darker | Keep them in a pouch or a small box. |
What to look for in the material
The material label tells you which metal a piece is made of and what kind of surface it has. In general, materials react differently to air and moisture, and with plated pieces, care plays a big part in how the surface looks. What helps most is a pair whose material you know and a routine that fits your day.
At Theia, Esme and the Clara necklace are rhodium-plated copper alloy with a bright silver-tone finish. Rhodium is a white, reflective metal from the platinum group that gives them their bright shine. Juliet is gold-tone copper alloy, and her gold tone looks its best when she gets a quick wipe with a soft cloth after wear and is stored dry. To read what the words on a material label mean, see what material is right for earrings.

What if your pair has already darkened?
Start with a soft, dry cloth and wipe the surface gently. That often lifts the film left by skin, perfume and air. Skip abrasive pastes, silver dips and long soaks, since they are too harsh for plated fashion jewelry. The easiest time is in the evening, right when you take your earrings out.
Where should your earrings go overnight?
A lot of care happens while you are not wearing your earrings at all. Put away dry, separately and closed, they meet less moisture and friction, and in the morning you pick up a pair that looks the way you remember it. To set up a spot for them, see how to store earrings. For the full routine, read how to clean your earrings.
