You take off a ring and there's a green mark underneath. It's alarming the first time, and it puts a lot of people off wearing jewellery altogether.

The good news: it's harmless, it washes off, and it's almost always avoidable once you know what causes it.

What's actually happening

The green isn't dirt and it isn't a reaction to silver. It's copper.

Copper reacts with the acids and salts in your sweat to form copper salts, which are green. Those salts transfer to your skin. That's the whole mechanism — chemistry, not an allergy, and nothing to do with the quality of your skin.

Where the copper comes from

Cheap base metals. Most inexpensive jewellery is brass or copper alloy with a thin plating over the top. As the plating wears, copper meets skin directly. This is the usual culprit.

Sterling silver, in small amounts. Sterling silver is 92.5% silver and 7.5% other metal, usually copper. That's a much smaller amount than in brass jewellery, and most people never see any discolouration from it — but it's why sterling silver can occasionally cause faint marking on people with very acidic skin.

Why it happens to some people and not others

Skin chemistry varies more than people realise.

Sweat acidity. More acidic sweat reacts faster with copper. This is largely genetic.

Diet and medication. Both change sweat composition. Some people notice marking appears during certain periods and not others.

Heat and humidity. More sweat means more reaction. Many people only see this in summer.

Lotions and soaps. Residue trapped between jewellery and skin accelerates it, particularly under rings.

If a friend wears the same piece with no problem while you get marks, that's why. It's not the jewellery being faulty.

How to stop it

Buy solid rather than plated base metal. Sterling silver contains far less copper than brass, and it's solid rather than a coating that wears through. This is the single biggest factor.

Look for a protective coating. A quality e-coating seals the metal and acts as a barrier between the piece and your skin.

Keep pieces dry. Remove jewellery before exercise, swimming and showering. Moisture is what starts the reaction.

Wipe after wearing. A soft dry cloth removes sweat residue before it has time to react.

Apply lotion first. Let it absorb fully before putting jewellery on.

Give rings a rest. Rings mark more than necklaces because they're pressed against skin in a warm, enclosed space. Rotating between pieces helps.

Removing the marks

Soap and warm water. That's it. The discolouration is on the surface of your skin and comes off easily. It'll also fade on its own within a day.

There's no need for anything harsher, and no lasting effect on your skin.

Is it an allergy?

Almost never. Green marking is a chemical reaction, not an immune response.

A genuine metal allergy looks different — redness, itching, a rash, sometimes blistering — and is usually caused by nickel, not copper. Nickel allergy affects a significant share of the population and is the reason many people believe they can't wear jewellery at all.

If you get itching and irritation rather than a green mark, nickel is the likely cause. Look for pieces that are explicitly nickel free.

How ANVIRA pieces are made

Every piece is solid 925 sterling silver — not brass, not copper alloy with plating over it. Our gold pieces are that same silver base, plated in 18K gold and sealed with a protective e-coating.

All our jewellery is nickel, lead and cadmium free.

We won't promise nobody will ever see a mark — skin chemistry is individual and anyone guaranteeing otherwise isn't being straight with you. But solid sterling silver with a sealed finish is the construction least likely to cause it.
