It's fine to get our jewelry wet! Wear it in the shower or while swimming, just make sure to dry it afterwards! If the item becomes dirty or tarnishes in some way, clean it using plain soap and water - drying with a soft cloth. Before storing the item, make sure it's fully dry and is not stored in a moist environment.
While wearing, avoid exposure to chemicals (including cleaning agents), and avoid wearing in environments where the item may be knocked.
