Why has my Pandora ring gone black?

Good day, I'm curious to understand why your Pandora ring has turned black. Have you noticed any changes in your daily habits or exposure to chemicals that might have caused this discoloration? It's important to consider the material the ring is made of, as certain metals like silver can tarnish over time. Could you provide more details about the cleaning and care routine you've been following for your ring? It's possible that a professional cleaning or polishing could restore its original shine.
