You find a ring you love, wear it for a week, and notice a faint green shadow where it sits. It is one of the most common questions we hear, and the reassuring answer is that it is rarely anything to worry about. With a little understanding of metals and a few simple habits, it is easy to avoid.
Why it happens
The green tint comes from copper. When copper meets moisture, warmth and the natural oils and salts on your skin, it reacts and leaves a light coloured residue behind. It is a surface stain rather than an allergy, and it washes away.
Copper is found in brass and bronze, and often sits beneath a thin layer of plating on inexpensive jewellery. Once that plating wears, the copper underneath comes into contact with the skin. Even sterling silver contains a small amount of copper, which is why it can occasionally tarnish.
Everyone's skin is a little different. Humid summer days, exercise and a snug fit all trap moisture against the skin, which is why the same ring may mark one person and not another.
Simple habits that help
- Take rings off before showering, swimming, washing up or exercising.
- Let hand cream and sunscreen dry fully before putting your rings back on.
- Apply perfume before you dress, rather than over your jewellery.
- Dry the skin beneath a ring after washing your hands.
- Store pieces somewhere dry, away from the bathroom.
If a mark appears
Wash the area with mild soap and warm water and dry it well. The tint usually fades within a day. Clean the piece gently with a soft cloth and a little warm soapy water, and dry it completely before wearing it again. Avoid abrasive cloths, which can wear away plating.
A green mark on its own is harmless. Itching, redness, swelling or a rash is different and may point to a sensitivity to a particular metal. If that happens, stop wearing the piece and speak to your pharmacist or GP.
Choosing pieces that stay beautiful
The best prevention begins with the metal itself. When choosing jewellery, look past the colour and ask what it is made from.
Stainless steel is one of the most reliable choices for everyday wear. It is strong, resists tarnish and is far less reactive than brass or copper alloys, so it is well suited to rings worn from morning through evening. Gold-toned stainless steel offers the warmth of gold with the resilience of steel beneath.
Solid gold of higher carats and platinum are also very stable, though they come at a higher price.
If you are ever unsure what a piece is made from, ask. A good jeweller will always be happy to tell you.
A considered choice
