Plated imitation gold jewelry tends to lose its color or tarnish over time due to several factors related to its materials and manufacturing process. Here are the main reasons:
Imitation gold jewelry is typically made from base metals (such as copper, brass, or zinc alloy) and coated with a thin layer of gold plating (often gold PVD or electroplating).
Over time, friction from wear, contact with sweat, or cleaning can wear away this thin layer, exposing the base metal underneath.
The base metals (especially copper and brass) react with oxygen, moisture, and acids in sweat, leading to oxidation and tarnishing.
Exposure to perfumes, lotions, chlorine (in swimming pools), and household chemicals can accelerate corrosion.
Low-quality plating processes may not bond well with the base metal, causing faster peeling or fading.
Uneven plating thickness can result in weak spots that wear off quickly.
People with more acidic sweat (higher pH) may notice faster discoloration due to accelerated chemical reactions with the metal.
Some imitation gold jewelry lacks a clear protective topcoat (like rhodium or sealant), making it more vulnerable to scratches and environmental damage.
Avoid contact with water, sweat, and chemicals.
Store in a dry, airtight container when not in use.
Clean gently with a soft cloth (no harsh abrasives).
Re-plate or apply a jewelry protector spray periodically.
If long-lasting color is important, consider higher-quality gold-filled or solid gold jewelry instead of plated options.
