Brooch, signed Sterling Craft, Coro, on applied rectangular plate, stunning flower design with three open back topaz glass prong set crystals, safety clasp, excellent original condition with lovely patina, the flower appears to be the same design as appears on page 49 of American Costume Jewelry, C4 "Roses" in a matching bracelet, patented in 1942, and is probably by the same designer, IMO, 4 x 1 3/4" substantial, very high quality early Coro piece.
