Short answer: A greenish color on the skin is often caused by copper reacting with sweat, moisture, the skin's natural substances, or products such as cream and perfume. It can also happen when copper is beneath a coating that wears away over time.

Why does jewelry turn your skin green? The green color is usually caused by a chemical reaction between copper in the jewelry and sweat, moisture, the skin's natural acids, or products such as cream and perfume. The reaction can form copper salts that settle on the skin. The mark can usually be washed off and is not in itself proof that the jewelry is fake or poor quality.

Why does jewelry turn your skin green?

Copper can react with moisture, salt, and acids around the skin. When the reaction occurs, green or blue-green compounds can form and rub off onto the finger, neck, or wrist.

This is often more noticeable on warm days, during exercise, or when the jewelry comes into contact with water, hand cream, perfume, or cleaning products.

Can 925 sterling silver leave green marks?

Yes, it can happen. 925 sterling silver consists of 92.5% pure silver and 7.5% other metals, often copper. Pure silver is relatively soft, so the alloy makes the jewelry stronger and more suitable for everyday wear.

Green discoloration can therefore also occur with genuine sterling silver jewelry. Color alone can neither confirm nor disprove the jewelry's quality.

Why does it only happen to some people?

How quickly a piece of jewelry reacts depends on both the material and how it is worn. Some people often notice marks, while others do not notice any at all.

• Sweat and moisture: Salt and moisture can increase the reaction with copper.
• Skin chemistry: Skin pH and composition vary from person to person.
• Cream and perfume: Cosmetics and skincare products can react with the metal.
• Water and cleaning products: Frequent contact can affect the surface.
• Wear: On gold-plated jewelry, the underlying metal can become more exposed over time.

How to avoid green marks from jewelry

• Take off your jewelry before bathing, washing your hands, cleaning, or exercising.
• Let cream and perfume dry completely before putting on your jewelry.
• Wipe the jewelry with a soft, dry cloth after use.
• Store jewelry in a dry place and separately to protect the surface.
• Always follow the care instructions for the specific material and surface finish.

How to remove the green color from your skin

Gently wash the area with lukewarm water and mild soap, then dry the skin thoroughly. Avoid scrubbing hard. If your skin itches, turns red, swells, or remains irritated, stop wearing the jewelry. Green discoloration and skin irritation are not necessarily the same thing.

Frequently asked questions

Does a green mark mean the jewelry is fake?

No. Discoloration can occur when copper reacts with moisture and skincare products, even when copper is part of an alloy with genuine silver. The mark alone therefore doesn’t tell you whether the jewelry is genuine.

Is the green color dangerous?

The surface color can usually be washed off. If you also experience itching, stinging, redness, or swelling, remove the jewelry and treat it as possible irritation or an allergic reaction.

How can I keep my jewelry looking good for longer?

Avoid unnecessary contact with water and chemicals, wipe your jewelry after use, and store it in a dry place. Read our complete guide to everyday jewelry care.

What to consider before buying

Don’t look at the design alone. Also check the dimensions, weight, base material, any plating, and care instructions on the specific product page. This makes it easier to choose jewelry that suits the way you actually plan to wear it.

Can plated jewelry change in appearance over time?

Yes. Gold plating and silver plating are surface finishes that can wear off with use. Water, perfume, creams, and friction can affect how quickly this happens.

What’s the best way to store jewelry?

Store them in a dry place, preferably separately, so they don’t rub against each other. Always follow the care instructions for the specific item.
