Why is my Pandora bracelet turning black?

I'm curious to understand why your Pandora bracelet is turning black. Could it be due to exposure to certain chemicals or cleaning agents? Have you noticed any changes in your skin's acidity or sweat levels? Additionally, is the bracelet made of a material that's prone to tarnishing or discoloration? Have you been wearing it in environments with high humidity or frequent contact with water? Understanding these factors could help us pinpoint the cause and find a solution to prevent further discoloration.
