Why Does Some Jewelry Turn Skin Green?

Many people have experienced the frustrating and unsightly phenomenon of jewelry turning their skin green. This can happen with rings, bracelets, necklaces, and even earrings. But why does it happen? What type of jewelry is most likely to turn your skin green?

This discoloration is usually the result of a chemical reaction between the metal and acids in the skin's sweat or moisture. The reaction produces copper salts that are green, and they transfer to the skin, leaving a greenish tint.

Several metals and alloys are known to cause skin discoloration due to their chemical composition.

  1. Copper: Pure copper is a common culprit because it easily reacts with acids in sweat to form copper salts.
  2. Brass: Brass is an alloy of copper and zinc that can also cause skin to turn green.
  3. Nickel: Some people are allergic to nickel, and prolonged exposure to nickel-containing jewelry can cause skin irritation (even if you weren't previously allergic) and green discoloration.

Alloys with high copper content: Some alloys used in costume jewelry may contain high levels of copper, which can cause skin discoloration when worn for long periods of time.

Choose jewelry made of hypoallergenic metals such as sterling silver, gold, platinum or titanium, which are less likely to cause skin reactions.

Apply clear nail polish to the inside surface of your jewelry to create a barrier between the metal and your skin, preventing direct contact and reducing the risk of discoloration.

Minimize contact between your jewelry and moisture and sweat, which can accelerate chemical reactions, by removing your jewelry before swimming, bathing or engaging in activities that may cause excessive sweating.

Clean your jewelry with a soft cloth and mild soap to remove accumulated sweat, grease or dirt, which can exacerbate skin reactions.

By understanding the chemistry of how certain jewelry turns skin green and taking preventative measures, people can enjoy wearing their favorite jewelry without worrying about unwanted discoloration or skin irritation.
