Answer
Exposed jewelry such as wristwatches, bracelets, earrings (including stud earrings) and neck chains, or any item judged dangerous by the umpire, may not be worn during the game.  

However from my experience if the stud earrings can be securely covered with safety tape to the satisfaction of the umpire she may leave them on (i.e. recently pierced ears).
