  • Why Does a Necklace Chain Turn Green?

The discoloration of your necklace chain is typically due to a chemical reaction. This reaction can be triggered by various factors, but the primary cause is often the metal composition of your necklace.


  • The Role of Metal Composition

Many affordable jewelry pieces are not made of pure silver or gold. Instead, they are often crafted from base metals like copper or nickel, which are then plated with a thin layer of silver, gold, or rhodium. Over time, this plating can wear off, exposing the base metal underneath.

When the base metal comes into contact with moisture, a chemical reaction known as oxidation occurs, causing the metal to tarnish or discolor. Copper, in particular, turns green or greenish-blue when it oxidizes, which is why your necklace chain may have turned green.


  • Other Contributing Factors

While metal composition plays a significant role, other factors can contribute to your necklace chain turning green. Body chemistry, for instance, can have an impact. People who have high acidity levels in their sweat may notice that their jewelry turns green more quickly.

Additionally, exposure to certain substances can accelerate the oxidation process. These include lotions, perfumes, soaps, and even certain types of food. Environmental factors, such as high humidity or pollution, can also contribute to your necklace chain turning green.


How to Prevent Your Necklace Chain from Turning Green

Now that we understand why a necklace chain might turn green, let's explore ways to prevent this from happening.


  • Choose High-Quality Jewelry

One of the most effective ways to prevent your necklace chain from turning green is to invest in high-quality jewelry. Pure gold and silver are less likely to tarnish compared to their plated counterparts. Stainless steel, platinum, and rhodium are also good options as they are resistant to oxidation.


  • Limit Exposure to Harmful Substances

Try to avoid exposing your necklace to substances that can trigger oxidation. Remove your necklace before swimming, bathing, or exercising, as the chlorine in swimming pools, the salts in seawater, and the sweat from exercise can all cause discoloration. It's also a good idea to put your necklace on last when getting ready, to minimize exposure to lotions and perfumes.


  • Regular Cleaning

Regularly cleaning your necklace can help to remove any substances that may contribute to oxidation. Use a soft cloth to gently wipe your necklace after each wear. For a deeper clean, use warm water and mild soap, but make sure to dry the piece thoroughly afterward.


  • Proper Storage

Store your necklace in a cool, dry place, and try to limit its exposure to air when not in use. Consider using anti-tarnish strips or bags for storage, as they can help to absorb substances in the air that cause oxidation.


What to Do If Your Necklace Chain Turns Green?

If your necklace chain has already turned green, don't despair. In many cases, the discoloration can be removed.


  • Cleaning

Start by cleaning the necklace with a soft cloth, warm water, and mild soap. If this doesn't remove the discoloration, you can try a jewelry cleaner designed for the type of metal your necklace is made of.


  • Professional Cleaning

For severe discoloration or valuable pieces, consider a professional jewelry cleaning. Jewelers have the skills and equipment necessary to clean your jewelry without causing further damage.


  • Re-plating

If your necklace is made of a base metal with a thin layer of gold or silver that has worn off, causing the discoloration, you may want to consider having it re-plated. A jeweler can apply a new layer of precious metal to the necklace, which can restore its original color and shine.


  • Replacement

In some cases, especially with low-cost jewelry, it may be more economical to replace the piece altogether. If you find that your jewelry often turns green, you may want to consider investing in pieces made of higher quality, more durable materials.


In conclusion, a necklace chain turning green is usually a result of oxidation, caused by the metal reacting with moisture and other substances. By understanding the causes, you can take steps to prevent this from happening and maintain the beauty of your jewelry.

From choosing high-quality pieces and limiting exposure to harmful substances, to regular cleaning and proper storage, there are many ways to keep your beloved necklace chain from turning green. And even if it does, remember that there are always solutions available to restore its original allure.

Remember, jewelry is more than an accessory; it's an expression of your style and personality. Don't let the fear of a little green tarnish hinder you from wearing your favorite pieces.

With the right knowledge and care, you can continue to shine in your chosen adornments without the unwanted green tinge.
