Pin measures 2 ½” in diameter and earrings are 1 1/8” in diameter.  Unsigned.

The set is in good condition.  There is some chipping to the enamel on the edges of the petals on all pieces.  The backs are more pink than the front.  I’ve never seen enamel color fade, so I think this is just the way it is made.  Nevertheless, this is a really cute set that you’ll enjoy wearing!
