For your consideration is a vintage enameled brooch or pin.  This brooch is in the shape of a goldfish or koi in a gold tone with blue and green enamel colors.  It has the accents of rhinestones for the fins, tail and eye.  Pin works well.   Measures 1 1/2" wide and 1 3/4" tall.  Pin works well on the back.
