Here is a nice possibly vintage enamel flower pin.  It measures 1.25 inches across and has a nice twist closure on the back.  It is unsigned so I don't know much about it.  I see a tiny spot on the edge where the gold is missing, but I didn't see it until I took a picture.  It's really tiny.  The enamel is good and the gold is thicker on the edge on some petals which adds character to the piece.
