Copper has been used in jewellery for centuries, and there’s a good reason it continues to be loved today. Its warm, earthy colour gives handmade pieces a natural character that is difficult to recreate with other metals.
But if you wear copper jewellery, you may eventually notice a green mark on your skin. So why does copper jewellery turn your skin green, and does it mean something is wrong with the jewellery?
The short answer is: usually, no. It is a natural reaction between copper, moisture, oxygen and your skin.

Why Does Copper Turn Skin Green?
Copper is a reactive metal. When copper jewellery comes into contact with moisture, sweat and oxygen, the surface can gradually react and form copper compounds. Some of these compounds can transfer onto your skin, leaving a temporary greenish mark.
How much this happens can vary from person to person. Your individual body chemistry, how much you sweat, the environment and how often you wear the jewellery can all make a difference.
So, if your copper ring, bracelet, earring or nose ring leaves a green mark, it doesn’t automatically mean that the jewellery is fake or poor quality. In fact, it is one of the natural characteristics of copper.

Is Green Skin From Copper Jewellery Harmful?
For most people, a green mark caused by copper jewellery is simply a cosmetic reaction and can usually be washed away.
However, if jewellery causes persistent irritation, itching, swelling or discomfort, stop wearing it and consider speaking to a healthcare professional. Not every skin reaction is simply copper oxidation.
It’s also worth avoiding claims that copper jewellery can treat medical conditions. While copper is an essential mineral in the body, there isn’t good evidence that simply wearing copper jewellery provides medical benefits.
What Makes Copper Jewellery Tarnish?
Copper naturally changes colour over time. Exposure to air, moisture, sweat, perfume, lotions and other substances can speed up the process.
Freshly polished copper can have a bright, warm appearance, while older copper may develop darker, deeper or more weathered tones. Some jewellery lovers actually prefer this natural patina because it makes each piece look more individual.
That’s one of the things I love about working with copper at Wah Artisan: your jewellery can develop its own character as you wear it.
How to Clean Copper Jewellery
Cleaning copper jewellery doesn’t have to be complicated. A soft jewellery polishing cloth is often enough to remove light tarnish and restore some of the copper’s shine.
For handmade jewellery, always be mindful of the design and finish. Aggressive scrubbing or harsh chemicals can alter a deliberately textured, hammered or oxidised surface.

Why Choose Copper Jewellery?
So, with all this talk about tarnishing, why choose copper?
Because copper has a unique warmth and personality, it works beautifully with earthy, rustic, minimalist and bohemian styles, and handmade copper jewellery can have a wonderfully organic appearance.
Unlike perfectly uniform mass-produced pieces, handmade copper jewellery can show subtle differences in texture, shape and finish. That’s part of its charm.

Copper Jewellery Trends & Styling
Copper jewellery works beautifully with many styles, from minimalist everyday pieces to bold statement looks. Textured, hammered, sculptural and earthy jewellery can add character to an outfit without feeling overly polished or uniform.
Try pairing a simple copper hoop with other understated pieces for an everyday look, or layer different copper textures and shapes for a more distinctive look.
Copper also pairs beautifully with natural materials such as wood, gemstones, beads and waxed cord, making it a great choice for earthy, rustic and bohemian-inspired styles.
