Copper Jewellery: What to Expect and Care

If you’re drawn to the warm, earthy glow of copper jewellery, you’re not alone. Copper has been used in adornment for thousands of years—not just for its beauty, but also for its unique properties. Here’s what you need to know about the copper chains in my shop, and how to care for them.

 

Solid Copper, Through and Through

The copper chains I use are bare solid copper—not plated or coated. That means the colour is copper all the way through, not just a surface layer. You won’t need to worry about a finish “wearing off,” because there is no plating to wear off. It’s the real deal.

 

Will Copper Tarnish?

Yes—bare copper naturally oxidizes over time, just like sterling silver. This is part of its charm and character. Oxidation is a surface-level reaction that causes the copper to darken or develop a patina with exposure to air and moisture. Some people love this evolving look, while others prefer to keep their copper bright and shiny.

If you want to restore the original shine, here’s how:

• Wash with dish soap to remove skin oils or dirt
• Soak in white vinegar for a few minutes
• Rinse, dry thoroughly, and buff with a soft cloth

There’s no coating or sealant that will permanently prevent copper from oxidizing. However, if you’d like to temporarily slow it down, you can apply Renaissance wax (reapply as needed). I don’t recommend lacquers—they tend to flake or peel with time.

 

What About Dark (Oxidized) Copper?

Some of the copper chains in my shop have an intentionally oxidized finish, also known as a patina. This gives the metal a rich, darker tone right from the start. However, this finish is not permanent—it’s surface-level and will gradually wear with use, especially in contact with skin or clothing. You can let it evolve naturally or polish it off if you prefer a brighter look.

 

Skin Reactions: Will Copper Leave Marks?

This is one of the most common questions I get, and the short answer is: it depends on your skin chemistry.

Copper, especially when worn bare and directly against the skin, can leave green or dark marks for some people. This is harmless and usually happens when:

• Skin is moist (from sweat, water, or humidity)
• You’ve been wearing the piece for an extended period
• Lotions and other products worn on the skin interact with the metal

Interestingly, if you can wear sterling silver without discolouration, chances are good that you can wear copper comfortably too. (Sterling silver is 92.5% silver and 7.5% copper, so it already contains copper.)

Other variables that may affect your skin’s reaction to copper include:

• Personal skin oils and pH
• Lotions or topical products
• Diet, medications, or health conditions

(Note, while I hold an honours degree in biology and strive to provide accurate information, I don’t claim to be a medical or dermatological expert—these observations are based on experience and customer feedback.)

 

The Bright Side of Bare Copper

Aside from its beauty, solid copper is free from nickel, cadmium, and lead, making it a great option for those with metal sensitivities—especially nickel allergies. Copper is also known for its anti-microbial properties, and while it’s not a medical device, some wearers (especially arthritics) have anecdotally reported benefits such as increased mobility when wearing copper jewellery.

 

Care Tips for Long-Lasting Beauty

To keep your copper chain looking its best:

• Avoid storing it in damp or wet areas, like on a vanity counter
• Like any jewellery, it’s best to remove it before exercising or showering
• Store it dry and clean, preferably in a fabric pouch or jewellery box

And remember: copper doesn’t rust—only iron rusts, and there is no iron in copper.

 

Whether you love the warm glow of bright copper or the rich, moody tones of oxidized patina, copper jewellery offers a timeless and versatile option—both beautiful and rooted in history. Embrace its evolution, or shine it up—it’s your story to tell.
