Once again I am going on a listing jag of vintage and costume jewelry, I have reasonable prices to sell!! Big brooch I believe is Boucher, wonderful enamel with some wear, the 2 screws in the back are not perfect, but hold fine with a tiny wobble. Please see my other auction for another Boucher piece, will be listing lots of Trifari and old pieces, some for s all repairs.. See photo for size. I return ONLY if I have misrepresented.
