Gold plated jewelry is a popular choice for those who love the look of gold but prefer a more budget - friendly option. However, a common question that arises among jewelry lovers is: Does gold plated jewelry tarnish? Tarnishing can turn a shiny piece of jewelry dull and discolored, which is a concern for anyone investing in these accessories. In this blog, we’ll explore the truth about gold plated jewelry tarnish, why it happens, and how to keep your pieces looking their best.
To put it simply, yes, gold plated jewelry can tarnish. Unlike solid gold, which is highly resistant to tarnishing due to its chemical stability, gold plated jewelry is not made entirely of gold. It consists of a base metal (such as copper, brass, nickel, or silver) covered with a thin layer of gold. While the gold layer itself is tarnish - resistant, the underlying base metal and the condition of the plating determine whether tarnishing will occur.
Tarnishing in gold plated jewelry typically doesn’t affect the gold layer directly but happens when the base metal is exposed. Over time, the thin gold plating can wear down or develop tiny cracks, allowing air, moisture, and other substances to reach the base metal. When this happens, the base metal reacts with environmental elements, leading to discoloration that becomes visible on the surface of the jewelry.
Understanding why gold plated jewelry tarnishes can help you take better care of your pieces. Here are the main factors that contribute to tarnishing:
2.1 Wear and Tear of the Gold Layer
The most significant factor is the thickness and durability of the gold plating. Gold plated jewelry has a very thin layer of gold, usually measured in microns (1 micron is 0.001 millimeters). Common plating thicknesses range from 0.5 microns to 2 microns, though some higher - quality pieces may have thicker layers.
With daily wear, activities like rubbing against clothing, handwashing, or even just moving your hands can cause the gold layer to wear away gradually. As the gold layer thins or gets scratched, the base metal underneath becomes exposed. Once the base metal is in contact with the air and moisture, it starts to react and form tarnish, which can appear as a dull film, dark spots, or even greenish hues (especially with copper or brass bases).
2.2 Reaction of the Base Metal
The type of base metal used in the jewelry plays a big role in how quickly tarnishing occurs. Here’s how common base metals react:
- Copper and brass: These metals are prone to reacting with sulfur in the air, sweat, or skincare products. This reaction creates a greenish or blackish tarnish that can seep through thin gold plating.
- Nickel: While nickel is less likely to tarnish on its own, it can cause skin irritation for some people. When combined with moisture, it may also contribute to the breakdown of the gold layer, indirectly leading to tarnish.
- Silver: Silver is known for tarnishing when exposed to sulfur, forming a dark gray or black layer. If silver is the base metal under gold plating, tarnish can develop once the gold layer is compromised.
Even if the gold plating looks intact, tiny pinholes or gaps (often invisible to the naked eye) can form during the plating process. These imperfections allow moisture and air to reach the base metal, triggering tarnish that eventually becomes visible on the surface.
2.3 Environmental and Lifestyle Factors
Your daily habits and the environment you expose your jewelry to also affect tarnishing:
- Moisture and humidity: Swimming, showering, or even sweating heavily while wearing gold plated jewelry can speed up the breakdown of the gold layer. High humidity in the air can also cause the base metal to react over time.
- Chemicals: Contact with chemicals in cosmetics, perfume, hairspray, lotion, and cleaning products can corrode the gold plating. These substances weaken the bond between the gold layer and the base metal, making tarnishing more likely.
- Storage conditions: Storing gold plated jewelry in damp places, such as a bathroom cabinet, or leaving it uncovered in a jewelry box exposes it to air and moisture. Storing it with other metals can also cause scratches and chemical reactions that lead to tarnish.
While gold plated jewelry can tarnish, there are steps you can take to slow down the process and restore its shine if tarnish appears.
3.1 Prevention: Keep Tarnish at Bay
- Remove jewelry before certain activities: Take off your gold plated jewelry before swimming, showering, exercising, or doing household chores. This avoids exposure to water, sweat, and harsh chemicals.
- Apply cosmetics first, then jewelry: Put on your perfume, lotion, and hairspray before putting on your gold plated jewelry. This way, the chemicals have time to dry, reducing their impact on the plating.
- Clean gently and regularly: After wearing, wipe your jewelry with a soft, dry cloth to remove sweat, oils, and dirt. For a deeper clean, mix a few drops of mild dish soap with warm water, dip a soft brush (like a toothbrush with soft bristles) into the solution, and gently scrub. Rinse thoroughly and dry immediately with a clean cloth.
- Store properly: Keep your gold plated jewelry in a cool, dry place. Store each piece separately in an airtight container, a jewelry pouch, or a box lined with anti - tarnish fabric. This minimizes exposure to air, moisture, and scratches.
- Choose quality pieces: Opt for gold plated jewelry with a thicker gold layer (look for plating labeled as 1 micron or more) and reputable brands. Thicker plating is more resistant to wear and tarnish.
3.2 Treatment: Fixing Tarnished Gold Plated Jewelry
If your gold plated jewelry has already tarnished, don’t panic. Here’s how to treat it:
- Mild soap and water: For light tarnish, mix mild dish soap with warm water. Use a soft cloth or cotton swab to gently rub the tarnished areas. Rinse well and dry completely. Avoid scrubbing too hard, as this can remove more of the gold layer.
- Baking soda paste: For slightly stubborn tarnish, make a paste with baking soda and a small amount of water. Apply it to the tarnished spots with a soft cloth, rub gently in circular motions, then rinse and dry. Use this method sparingly to prevent damaging the plating.
- Avoid harsh cleaners: Never use silver polish, metal cleaners, or abrasive tools (like steel wool) on gold plated jewelry. These products will strip away the gold layer, making the tarnish worse and ruining the piece.
- Consider re - plating: If the tarnish is severe and the base metal is clearly exposed, professional re - plating is an option. Many jewelry repair shops offer this service, which can give your favorite pieces a new lease on life.
In conclusion, while gold plated jewelry can tarnish due to its base metal composition, thin gold layer, and environmental factors, it doesn’t have to lose its shine permanently. By understanding why tarnishing happens and following the prevention and treatment tips above, you can extend the life of your gold plated jewelry. With proper care, you can enjoy your favorite pieces for years to come, keeping them looking as beautiful as the day you bought them. Remember, a little attention goes a long way in preserving the luster of gold plated jewelry!
