When earrings turn your ears green it means the metal is corroding against your skin. Copper in the earring reacts with moisture and skin acids, forms green copper compounds, and those deposit on the skin around the piercing. It isn't a sign of poor hygiene, an allergy, or fake jewelry. It's a reliable signal about the material. Our materials page explains what we use instead.
What it means when earrings turn your ears green
There's copper in the earring, and it's reaching skin. Copper is the cause in almost every case. It's in most low-karat gold, all rose gold, brass, and the remaining portion of sterling silver.
The metal is actively corroding. Not slowly deteriorating in a drawer, but reacting right now, at the point of contact, because a pierced ear is warm, slightly damp and mildly acidic.
Material is transferring into skin, not just onto it. What you can see is the visible deposit on the outside. The same process is happening inside the piercing channel, where skin is thinner and more permeable.
If it's a plated pair, the coating has probably worn through. Plating goes first at the post and the back, where friction concentrates. The front can still look perfect.
What it doesn't mean
It doesn't mean she's allergic. Green staining is a chemical reaction on the skin's surface, not an immune response. She might separately be developing a sensitivity, and the mark itself isn't evidence of it.
It doesn't mean the jewelry is fake. Plenty of genuine, correctly hallmarked gold contains copper. A hallmark certifies the gold content, not the rest of the recipe.
It doesn't mean she's dirty, or that you didn't clean them enough. This has nothing to do with hygiene, and cleaning changes nothing about the reaction.
It isn't dangerous in itself. The mark washes off with soap and water and does no harm on its own.
It isn't something you caused. The material was decided before you saw the product.
Why it matters anyway
The stain is harmless. What it's a symptom of is worth attention.
Green means reactive metal is in continuous contact with skin, including inside the piercing. Prolonged exposure to reactive metals is the mechanism behind sensitization, which is how a metal allergy develops.
Nickel allergy affects around one in five people in North America, and the American Academy of Pediatrics reported in 2020 that nickel allergic contact dermatitis in children has nearly quadrupled over three decades, with at least 1.1 million children in the United States already sensitized. Sensitization is cumulative and generally permanent once it happens.
The copper causing the green isn't usually the metal that causes the allergy. But a piece releasing copper freely is a piece whose alloy is unstable and undisclosed, and unnamed alloys are where nickel tends to be too.
So read a green mark as a message about the whole piece rather than as a cosmetic issue with one part of it.
Why it happens more at some times than others
Heat and sport, because perspiration increases.
Summer, for the same reason, plus sunscreen sitting on the lobe.
After swimming or bathing, where moisture is trapped between metal and skin.
As a pair gets older, because a coating that was protecting the base metal has worn through.
On one child and not another, because skin chemistry varies. How much she perspires and its composition change how quickly the reaction runs.
What to do about it
Take that pair out and see how quickly it stops.
Note which pair. Two or three entries usually reveal a pattern, and this is the reason so few reactions ever get traced to a specific product.
Check the post. A darker steel color where the front still looks gold means the coating has gone.
Jewelry on last, off first. Perfume, sunscreen, lotion and soap all accelerate it.
Then look at what the next pair is made of. A named metal with a grade, all the way through to the post and the back. Not an adjective.
If the ear is also red and hot, swollen, discharging or increasingly painful, that's a separate matter and one for your pediatrician.
What we do
purepixxi uses two materials, and neither contains copper as a structural component.
S316L Surgical Steel, the same grade used in medical instruments and implants, chosen because it resists corrosion and therefore releases very little. On the Polished Surgical Steel range that's the whole earring, one material throughout.
24K Pure Gold, which is pure 24 karat gold finished onto a solid S316L Surgical Steel core with Aunix™ 24K, our engineered gold finish. At 24 karat there's no alloy in the gold, so there's no copper in the finish. It's a gold-plating process and we say so. The difference is what we plate and what we plate it onto.
We don't make rose gold, because the pink color is the copper.
The setting, the post and the butterfly back all carry the same core. Independently tested by SGS to ASTM F2923 and CPSIA, with nickel release not detected under EN 1811 and lead below a tenth of the United States legal limit. Report BTO 341803/1, and you can ask me for it.
You can see the range on the 24K Pure Gold collection.
The plainest way to rule this out is a pair with nothing plated over anything, which is what the 4mm Ball Stud Earrings in Surgical Steel are.
Questions parents ask next
Does it stain permanently? No. It's a surface deposit and it washes off with soap and water.
Will it happen to every child in the same earrings? Not necessarily. Skin chemistry varies, so one child can mark and another can wear the same pair without any sign of it.
Does it mean I wasted my money? Not if she likes them. It means those earrings suit occasional wear rather than daily wear, because the problem is cumulative contact.
Are green marks worse than black ones? They point at different causes. Green is copper corroding. Black is usually abrasion or a reaction with products applied to the skin.
Could a jeweler fix it? Replating would restore the barrier temporarily. It doesn't change the base metal underneath, so the same thing happens again once the new layer wears.

About the author. Matt Westmore is the founder of purepixxi. He came to children's jewelry from manufacturing and sourcing rather than marketing, which means he has walked the factory floors and knows what is actually inside a product rather than what a label says about it. purepixxi uses two materials only, names them exactly, and has them independently tested.
