Why Does 925 Silver Turn Yellow?
925 sterling silver is made of 92.5% pure silver and 7.5% alloy metals such as copper. Over time, exposure to air, sweat, and chemicals can cause the surface to discolor. While tarnish usually appears black, some sterling silver may develop a yellowish tint before darkening completely. This reaction is natural and does not mean the silver is fake or low quality.
Main Causes of Yellowing
Several factors contribute to yellow discoloration on sterling silver jewelry:
| Cause | Why It Happens | Prevention |
|---|---|---|
| Air & humidity | Oxidation of alloy metals | Store in airtight pouch |
| Sweat & oils | Skin contact accelerates reaction | Wipe jewelry after wearing |
| Chemicals | Perfume, lotion, or chlorine exposure | Remove jewelry before swimming or showering |
| Long-term storage | Improper storage leads to oxidation | Use anti-tarnish cloth or strips |
How to Clean Yellowed Silver
To restore shine, gently polish your jewelry with a silver polishing cloth. For heavier discoloration, soak the piece in warm water with mild soap, then dry thoroughly. Baking soda paste or professional silver cleaning solutions can also remove yellow stains. Always avoid harsh abrasives that may scratch the surface.
Conclusion
Yes, 925 silver can turn yellow due to natural oxidation and environmental factors. This does not mean it is fake; it is a normal reaction of sterling silver alloys. With proper cleaning and storage, yellowing can be removed, and your silver jewelry will maintain its brilliance for many years.
