Why Does My Jewelry Tarnish and How Can I Restore Its Shine?

Tarnishing is a common issue that affects many types of jewelry, leading to a loss of luster and sometimes even causing beautiful pieces to appear dull and unattractive. Understanding why tarnishing occurs and knowing how to restore and maintain the shine of your jewelry can keep your collection looking splendid for years to come.


Understanding Tarnishing in Jewelry

What is Tarnishing?

Tarnishing is a chemical reaction that occurs on the surface of metals, such as silver, gold, and copper. This reaction usually results in a dark, sometimes black coating known as tarnish. The primary cause of tarnishing is exposure to air and environmental chemicals, especially sulfur dioxide and oxygen.


Common Causes of Tarnish

  • Silver and Copper Jewelry: These metals are particularly prone to tarnishing because they react with sulfur compounds found in the atmosphere and in household substances like rubber bands, wool, and certain foods.
  • Gold Jewelry: While pure gold doesn't tarnish, gold alloys can. The metals mixed with gold, such as copper and silver, can react and cause tarnishing.
  • Environmental Factors: High humidity, pollution, and exposure to chemicals, including those found in perfumes, lotions, and cleaning products, can accelerate the tarnishing process.

How to Restore Shine to Tarnished Jewelry

Please note that while these cleaning methods are generally safe for a wide range of jewelry, they may not be suitable for all types of gemstones or delicate settings. It's always best to consult a professional jeweler or refer to the care instructions specific to your jewelry before attempting any cleaning or polishing at home. Using incorrect methods can cause damage to delicate pieces.

Cleaning Silver Jewelry

For silver jewelry, a simple and effective home remedy involves using baking soda and aluminum foil:

  1. Line a bowl with aluminum foil, shiny side up.
  2. Place the tarnished silver on the foil.
  3. Sprinkle baking soda over the jewelry.
  4. Pour boiling water over it; the chemical reaction will transfer the tarnish from the jewelry to the foil.
  5. Remove the jewelry, rinse under cool water, and polish with a soft cloth.

Cleaning Gold and Gold Alloy Jewelry

Gold jewelry, especially those with a higher karat, can usually be cleaned with a gentle cleaning solution:

  1. Mix a bit of mild dish soap with warm water.
  2. Soak the jewelry for about 15 minutes.
  3. Use a soft brush, like a soft toothbrush, to gently scrub the jewelry.
  4. Rinse thoroughly with lukewarm water and dry with a soft cloth.

Cleaning Gemstones

Be careful when cleaning tarnished jewelry with gemstones, as some stones can be damaged by heat or chemicals:

  1. Use a mild soap and water solution.
  2. Apply the solution with a soft cloth or brush, taking care not to soak the stones, especially if they are porous or fracture-filled.
  3. Dry with a lint-free cloth.

Preventive Measures to Avoid Tarnishing

  • Store Jewelry Properly: Keep jewelry in a dry, cool place away from direct sunlight. Use anti-tarnish strips in your jewelry box or store pieces in anti-tarnish bags.
  • Wear Jewelry Wisely: Avoid wearing jewelry while using chemicals, swimming, or exercising, as sweat and chlorine can accelerate tarnishing.
  • Regular Cleaning: Regularly clean your jewelry even when it's not visibly tarnished to remove oils and dirt that can start the tarnishing process.

Polishing and Professional Care

For heavily tarnished pieces or delicate, high-value items, consider professional cleaning. Jewelers have specialized tools and solutions that can restore jewelry without the risk of damage.


Understanding the causes of tarnishing and knowing how to handle it can help you maintain the beauty and longevity of your jewelry. With regular care and proper storage, you can keep your favorite pieces sparkling for every occasion.
