do pandora bracelets turn copper or make your wrist green?

i plan to buy one for my mom for mothers day.. the gold bracelet chains are too expensive.. and the silver ones are lik $50.. would those like defect?

if you buy a sterling silver one, you won’t have any problems. Don’t buy a silver plated one, the plating will wear off and the base metal underneath will come through.
Your mum is lucky though, sounds like a nice gift for her.
