 73 Coro - Patent #110296 This dress clip is 2 1/4 X 1 inch. So the question is, was this made as part of a Duette, or was it made as a stand alone clip? The flowers on the other Duette I have are only 1 1/4 X 3/8 inches. The over all Duette is 1 3/8 X 1 inch and are fur clips.
|  74 CoroCraft - Patent #154396 The flower on this Duette was patented as a brooch, but made as a Duette Fur Clip. I found no patent for this Duette.
|  75 Coro - Patent #176670 This earring has the same leaf and stone placement as this Coro necklace. I found no patent for this necklace.
|  76 Trifari - Patent #155215 This patent is for an earring, but this piece is a brooch. There is no patent for a brooch.
