If you’ve ever taken off a ring or necklace and noticed a faint green mark on your skin, don’t panic — it’s not a sign of low-quality jewelry or an allergic reaction. It’s actually a super common chemical reaction that happens to many people (even with good jewelry!). The best part? It’s easy to understand and easy to prevent.
Let’s break down why jewelry sometimes turns skin green, what causes it, and how to keep your everyday pieces looking — and feeling — flawless.
What Actually Causes the Green Marks?
That green color comes from a reaction between copper (a metal commonly found in jewelry alloys) and elements like moisture, sweat, lotions, and your skin’s natural pH.
This reaction creates copper salts, which can transfer to your skin and leave a temporary green tint.
It’s harmless, painless, and washes off easily.
Why Copper and Brass React This Way
Copper and brass (a copper alloy) are often used in jewelry because they’re strong, durable, and have a beautiful warm tone.
But when exposed to:
-
Sweat
-
Water
-
Oils
-
Perfume
-
Lotion
-
Humidity
…the metal can oxidize, leading to that green tint.
Fun fact: This is the same patina effect that makes the Statue of Liberty green.
How Your Skin’s pH Affects Reactions
Your natural skin pH plays a big role.
More acidic skin = more reactions
If your skin runs slightly acidic (common for many people), it accelerates the oxidation process.
Other factors include:
-
Medications
-
Body chemistry
-
Sweat levels
-
Lotions or products on the skin
According to dermatologists at the American Academy of Dermatology, skin pH variations are completely normal — and they’re a major reason reactions differ from person to person.
Which Metals Commonly Cause Green Marks?
1. Copper
The most common cause.
2. Brass
Contains copper, so it can react similarly.
3. Bronze
Another copper-heavy alloy.
4. Low-quality metal mixes
Cheaper jewelry often has higher copper content.
5. Nickel (Note)
Nickel usually causes rashes/itching, not green marks. That’s an allergic reaction — different from copper oxidation.
Good news: Malibu Sunday uses nickel-free, sensitive-skin-friendly materials.
Why Malibu Sunday Jewelry Doesn’t Usually Turn Skin Green
Our pieces use 18k gold plating over high-quality nickel-free brass, which creates a protective barrier between your skin and the metal.
When cared for properly, the gold layer prevents oxidation and keeps your jewelry looking bright.

How to Prevent Jewelry From Turning Skin Green
Here’s how to keep your gold-plated pieces clean and reaction-free:
1. Keep Jewelry Dry
Remove pieces before:
-
Showering
-
Swimming
-
Working out
-
Applying lotion or perfume
2. Store Correctly
Use soft pouches or separate compartments to minimize oxidation.
3. Clean Gently After Each Wear
Wipe with a dry microfiber cloth to remove oils and sweat.
4. Avoid Sleeping in Jewelry
Nighttime sweat + pressure can wear down plating faster.
5. Choose High-Quality Plating
Thicker gold plating (like Malibu Sunday’s 18k gold layer) helps prevent reactions.
