Does White Copper Jewelry Tarnish?

Yes, white copper jewelry does tarnish.

While the term "white copper" might imply a specific alloy resistant to tarnishing, it generally refers to copper that has been treated or plated to achieve a silver-like appearance. However, beneath the surface, it still contains copper, which is highly susceptible to tarnishing. According to information available, copper is quicker to tarnish than gold or sterling silver because of the oxidation process.

Why Does White Copper Tarnish?

Here's a breakdown of why white copper jewelry tarnishes:

• Oxidation: Copper reacts with oxygen in the air, causing it to oxidize. This reaction forms a dark-colored layer on the surface.
• Exposure to Sweat and Chemicals: As noted in the reference, copper reacts to various substances, including sweat, chlorine, and chemicals found in lotions and even your own skin. This exposure accelerates the tarnishing process.
• Skin Acidity: Individual skin chemistry can also affect how quickly copper tarnishes. Those with more acidic sweat may notice their jewelry darkening faster.

The Result of Tarnishing

When white copper tarnishes, it typically:

• Turns black or develops a dark patina.
• May leave a green stain on the skin.

Protecting Your White Copper Jewelry

While tarnishing is inevitable, you can take steps to slow the process:

• Store Properly: Keep your jewelry in airtight containers when not being worn to minimize exposure to air.
• Avoid Moisture: Remove your jewelry before showering, swimming, or engaging in activities that may cause you to sweat excessively.
• Limit Chemical Exposure: Avoid contact with lotions, perfumes, and household cleaning products.
• Clean Regularly: Use a gentle jewelry cleaner specifically designed for copper to remove any tarnish buildup.

By following these tips, you can enjoy your white copper jewelry for longer.
