Why is my Pandora bracelet going black?

I'm curious to know, why exactly is your Pandora bracelet turning black? Could it be due to exposure to certain chemicals or environmental factors? Have you been wearing it while engaging in activities that could potentially cause discoloration? Alternatively, is it possible that the bracelet's finish has worn off over time, revealing the base metal beneath? Understanding the root cause of this issue is crucial in determining the best course of action to restore your bracelet's original beauty.
