Why Does My Jewelry Turn Copper Green?

Pure silver is too fragile to make jewelry from, so it must be combined with copper and other cheaper metals to increase malleability and prevent it from corroding and turning your skin green.

Every time you bathe, shower, use lotion, apply perfume or deodorant or do the dishes, your jewelry is exposed to chemicals which could tarnish it. Learn what causes tarnishing so you can stop this problem from occurring in the future.

Chemical Reactions

Copper is an element that interacts with many substances, including sweat, lotions and certain other chemicals on the skin. Copper’s interactions can leave green or black/red marks depending on what it comes in contact with; additionally it may tarnish other metals such as silver or gold through an oxidation process known as “oxidation”, discoloring jewelry over time and discoloring it to look dull or yellowish – this should not be taken as an indication of poor quality or defect; it’s simply part of nature! This process happens naturally across metals exposed to air and chemicals present on human bodies as well as environmental elements present on Earth – something other metals don’t do!

Jewelry makers use different metals in combination to increase tensile strength and durability of jewellery items. Pure gold may be too soft for use as jewellery, so it is combined with other metals like copper to strengthen and more malleable it. Pure silver may not hold up against wear and tear as easily, so jewelry designers mix pure silver with copper or other elements such as zinc or nickel to form alloys; though these metals might not last as long as silver or gold, but still far more so than pure copper alone.

Copper forms an oxide layer as an anticorrosion measure when combined with other metals, creating an appearance similar to that of dull and green rings. Sometimes this layer may even make copper rings appear less bright from within than their shiny silver or golden exteriors may suggest. This layer also accounts for their dim and often green tone.

Copper jewelry, particularly bracelets, are popularly purchased due to its healing properties. Copper helps the body absorb copper as needed – although too much may give skin an uninvited green tint.

One effective way to prevent green skin from forming on copper jewelry is through regular cleaning. A combination of lemon juice and salt can effectively remove stains while polishing the piece of jewelry. Simply combine a small bowlful of salt with some lemon juice in another, dip your copper ring into the solution for several minutes before brushing away any sludge with a toothbrush before rinsing thoroughly and drying before storing in a safe location.


Copper jewelry in direct contact with skin can cause discolorations due to reacting with oils and chemicals in your body; this is especially troublesome when worn tight against skin like bracelets or rings.

Avoiding greening of jewelry requires regular maintenance. Use a lint-free cloth to buff away tarnish with ease; Ketchup also works well to clean copper jewellery as the vinegar in it helps dissolving any oxidation. Simply apply some Ketchup to the item you want to clean before rubbing with fingers, cloth or brush until all tarnish has vanished – then rinse well and dry completely before wearing again.

Make the most of lemon juice to restore and keep your jewelry looking brand new by immersing it in lemon juice for several minutes in a glass or plastic bowl, before using a microfiber cloth to buff away tarnish on copper pieces and remove tarnish altogether. Or combine equal parts baking soda and lemon juice to form a paste to rub on intricate pieces – especially useful in reaching difficult-to-reach spots on jewelry pieces!

Copper is an invaluable metal that finds applications across numerous fields, from medical supplies such as bandages and towels, to beauty products like makeup, hair dyes, and perfumes. Copper’s antimicrobial and antifungal properties make it useful for hospital materials like bandages and wound dressings; additionally it is often combined with precious metals like silver and gold alloys to strengthen and support them where their structures would otherwise be too soft – something we do at OBJKTS with our 925 sterling silver jewelry pieces that contain trace amounts of copper for strength.


Many people wear jewelry that contains copper and other metals, like silver or gold plating that protects it from reacting with your skin. Unfortunately, there are copper-based products without precious metal plating that could react with it more directly if exposed to sweaty hands or moisture from activities like gym workouts or showering. It’s therefore recommended that jewelry should be removed prior to entering any activity that requires coming in contact with water and sweat such as gym classes, showering or taking the gym membership exams.

Moisture on your hand or fingers can also lead to green-tinged jewelry. Moisture triggers chemical reactions that eventually turn it green. Regular jewelry cleaning using a polishing cloth is also recommended in such instances.

Ketchup can also help remove the tarnish from copper pieces by applying a small amount of the condiment and using your fingers, cloth or toothbrush to rub over it until all traces of ketchup have been washed away from your piece. After which, rinse carefully to make sure there are no lingering remnants left behind.

Vinegar can also be an effective copper cleaner. Pour some vinegar in a glass or plastic bowl and allow your jewelry to soak for several minutes before rinsing and drying it with a soft cloth. Alternatively, commercial cleaners designed specifically to clean jewelry may work as well – simply follow instructions on their labels for use.

On occasion, you may wish to wear your jewelry without regularly cleaning it. This can be accomplished if worn in an environment without excessive amounts of sweat or water exposure; copper pieces can also be protected with a coat of varnish which prevents them from tarnish and staining; regular touch ups will need to be performed on this varnish coating in order to keep its integrity.


Copper is an invaluable metal that serves many functions. When alloyed with zinc it forms various brasses; when added to nickel it creates nickel silver jewelry; it can even be used to produce verdigris which is commonly found in paints and dyes. Finally it’s often seen in craft and art jewelry sold widely – as well as fashion jewelry!

One of the main causes of jewelry turning green is due to coming into contact with chemicals found in body lotions, perfumes, deodorants and other personal care products that contain copper. When exposed to these chemicals they react with it to form an opaque dark green or black coating known as patina which is difficult to remove without risking damaging its structure.

Sweat can also cause jewelry to turn copper, with sulfuric compounds reacting with copper in jewelry to form chelated deposits that interact with skin-absorbent chemicals to produce green discolorations on many types of hoop earrings and necklace chains that come into close contact with it.

Jewelry that is plated with gold may not immediately turn green, though over time it could discolor if its protective gold coating wears off, exposing its copper base metal base. While sterling silver-plated pieces may discolor as well, this typically happens less often as this shield protects the copper from reacting with chemicals on skin surface.

Copper in itself is not harmful, but high concentrations can be toxic and lead to various health problems when inhaled or touched by skin contact. Furthermore, when heated and burned with air pollutants such as sulfates and nitrates present it may produce metal fume fever symptoms – an adverse health reaction similar to allergic reaction from touching.
