Copper jewellery: care, cleaning and green marks on skin
Pictured: the Old City copper necklace, worn.
Copper has a warm colour, a lively surface and a distinctive character. Yet choosing a copper piece often raises a question: “Will it leave green marks on my skin?” Followed by: “How do I clean it without damaging it?”
A few simple habits are enough to care for it. Start by understanding its finish: polished copper is not necessarily cared for in the same way as patinated copper with a protective coating.
Why can copper leave green marks on skin?
Copper can react with perspiration, moisture and ingredients in creams and cosmetics. Some reaction products can transfer to the skin, leaving a greenish colour. This is not a test of the jewellery’s quality and does not mean your body needs copper.
A colour mark is different from irritation. If itching, redness or discomfort occurs, remove the jewellery and seek medical advice if symptoms persist.
What makes our copper jewellery different?
The patinated copper jewellery with natural gemstones in our selection is also treated with a polymer solution that creates a protective coating. The dark patina highlights the gemstones, while the protective treatment helps limit contact between the copper, skin and external agents.
This does not make the jewellery waterproof or unchanging: friction, wear and harsh products can gradually wear down the protection. The aim is to preserve the finish rather than polish the metal back to a bright shine.
Explore these contrasts in our copper jewellery collection, from raw gemstones to druses and multicoloured compositions.
Three small tricks using things you already have at home
1. A clean, dry glasses cloth
A soft lens cloth, clean and free of impregnated cleaning products, is a simple ally. After wearing your jewellery, gently wipe accessible surfaces to remove fingerprints and surface residue.
There is no need to rub hard. Avoid cloths impregnated with silver or copper polish: they serve a different purpose and can alter the finish. On the copper ring with raw amethyst, for example, the contrast between the gemstone and dark setting is part of the design.
2. Reuse a silica gel sachet
The small sachets found in some packaging can help limit moisture in a well-closed jewellery box. Choose an intact, clean and dry sachet; do not open it or pour its contents over jewellery.
Put the jewellery away only when it is already dry, keeping pieces separate to prevent rubbing. The sachet is a small storage aid, not a guarantee against oxidation. Keep it away from children and pets.
3. A shower often removes marks from skin
As I often tell people trying on our jewellery: “Usually, it washes off in the shower.” This refers to the mark on your skin. Remove the jewellery first, then gently wash the area with soap and water. There is no need for salt, lemon or abrasive sponges.
A shower is not a way to clean the jewellery itself. Take it off beforehand to help preserve the treatment and gemstones.
A memory of my grandmother and copper folklore
My grandmother interpreted that green mark as a sign that the body was taking from the copper what it needed. It is a family memory, part of the folk explanations passed down from one generation to the next.
Folk traditions also attribute benefits against inflammation and joint pain to copper. These are grandmother’s stories, not medical advice. Green marks do not demonstrate useful copper absorption or a deficiency. Clinical studies of copper bracelets have not demonstrated specific benefits for arthritis pain and inflammation compared with placebo.
A piece of jewellery can be valued for its beauty, the memories it carries and its personal meaning. We do not offer it as a treatment, and it does not replace medical care or advice.
Home remedies to avoid on your jewellery
Lemon, vinegar, salt, baking soda and toothpaste often appear in household metal-polishing tips. We do not recommend them for our patinated, protected jewellery: they can alter the finish and are not universally suitable for natural gemstones.
Also avoid soaking, boiling water, solvents and abrasive sponges. Remove jewellery before swimming, showering, cleaning and activities that make you perspire. Let creams and perfume dry before putting it on.
When to ask for advice
If you notice a marked surface change or recurring marks, contact us before attempting DIY polishing. We can consider the best care for your piece together.
