Cleaning: To maintain its luster, occasionally clean with a soft cloth and avoid exposure to harsh chemicals. Consider using a cleaner specifically for copper, such as Wright's Copper Cream, and follow manufacturer's directions.
Waxing: After cleaning, apply a thin layer of beeswax or other high-quality commercial protective wax such as Renaissance wax, to protect the copper and deter tarnish.
Avoid Chemicals and Humidity: Keep copper away from chemicals and humid conditions to prevent tarnish. Store copper jewelry away from direct sunlight to prevent oxidation.
Storage: Store in a cool, dry place. A zip-lock bag can reduce air exposure and slow down tarnishing.
Green Discoloration on Skin:
- Natural Patina Formation: Copper jewelry develops a green patina over time due to exposure to air (oxygen) and moisture. This is a natural process where the copper reacts to form copper carbonate.
- Harmless on Skin: The green patina on copper jewelry is generally harmless. However, it can sometimes cause skin discoloration when worn, leaving a greenish tint. This is not harmful but might be undesirable for some wearers. A clear coat of nail polish can be applied occasionally to inhibit this.
- Aesthetic Preference: The verdigris or green patina is often appreciated for its unique, rustic appearance. Many people value this natural aging process, as it gives the jewelry character and a vintage look.
- Preventing Patina Formation: To slow down or prevent the formation of a patina, you can seal your copper jewelry with a high-grade wax, such as Renaissance wax. This needs to be reapplied periodically, as it can wear off over time.
- Skin Sensitivity: For individuals with sensitive skin, the reaction between the copper and skin oils may cause irritation in addition to the green discoloration. In this event, stop wearing the copper item.
The green patina on copper jewelry is a natural occurrence that many find appealing, though it can be controlled or cleaned depending upon personal preference. Regular maintenance and protective coatings can help preserve the original look of the jewelry while minimizing skin discoloration.
