For those that wonder how big these are, they are the exact size of a nickel.  I laid an earring on top of a nickel and the exterior of the earring fit to the edge of the coin.  These are sweet and the stones are a modest size making the earrings look like the might be real.  Lots of sparkle but not so big they look like dime-store fakes.  The clasp seems to be sturdy but I treat them gently and don't sleep  in them
