Generally speaking, it's best to avoid wearing sterling silver jewelry in the shower. While the silver itself won't tarnish in the water, soaps and shampoos often contain sulfur, which can accelerate tarnishing. Additionally, lingering moisture—especially in hard-to-reach areas like behind a pendant—can promote tarnish. To keep your jewelry looking its best, it's a good idea to remove it before showering and dry it thoroughly if it gets wet.
