These are a little smaller than I expected, but I probably wear them more because of it.  (As another reviewer noted, they're slightly smaller than a dime.  Either these reviews weren't there when I ordered them or I wasn't paying attention.)  They're not special-occasion jewelry for an adult, but they're great for wearing daily to work or something.  They're very light and comfortable, and after wearing them almost every day for the past few months, they still feel sturdy and like they will last a long time.
