Rings don't actually turn into copper. What appears to be copper is usually tarnish or corrosion on the surface of the metal due to chemical reactions. Here's a breakdown of the reasons:
1. Tarnish from Chemical Reactions:
-
Contact with Substances: The primary reason rings appear to turn copper-colored is due to tarnish caused by reactions with substances you encounter daily. These include:
- Body Oils and Sweat: Your skin's natural oils and sweat contain acids and salts that can corrode the metal.
- Cosmetics: Makeup, lotions, perfumes, and hairsprays often contain chemicals that react with the ring's metal.
- Household Chemicals: Cleaning products and other household chemicals can accelerate tarnishing.
- Sulfur: Exposure to sulfur compounds in the air or in certain fabrics can also contribute to tarnishing.
-
Base Metals: Many rings are made of alloys (mixtures) of different metals. The base metals (like copper, nickel, or silver) are more reactive than precious metals like gold or platinum. When these base metals corrode, they can create a surface layer that appears copper-colored.
2. Copper in Alloys:
- Alloy Composition: Even gold or silver rings often contain copper as an alloying agent to increase durability. When the other metals in the alloy corrode or wear away, the copper can become more exposed, giving the ring a copper-like appearance. This is particularly noticeable in lower-karat gold jewelry.
3. Skin Reactions (Less Common):
- Metal Sensitivity: In rare cases, a reaction between your skin and the ring's metal can cause a reddish or copper-colored stain on your skin, which might be mistaken for the ring turning copper. This is more likely with nickel.
How to Prevent Rings from "Turning Copper":
- Remove your ring during activities: Take off your ring when washing your hands, showering, swimming, cleaning, or applying lotions or perfumes.
- Clean your rings regularly: Use a jewelry cleaner specifically designed for the metal your ring is made of.
- Store your rings properly: When not wearing your rings, store them in a jewelry box or pouch to protect them from air and moisture.
- Consider hypoallergenic metals: If you are sensitive to certain metals, choose rings made of hypoallergenic materials like platinum, titanium, or surgical stainless steel.
