We found this monstrous brooch at a very upscale estate sale where we found many modern Danish and Scandinavian pieces of fine jewelry. This appears to be a boutique piece that unfortunately has no marks on the back and aside from the ammonite fossil in the middle has us stumped. It did come with an original price tag of $175 and on the reverse is written ?OWESS?. We think it has silver, bronze and copper mixed in and we did do a scratch acid test using 18K acid and the result did turn blue indicating a presence of silver though how much is anyone?s guess. So if you like brooches that look a bit like a mangled wreck but feature a dove/bird flying over ammonite, this is your piece and you should grab it! If you recognize the work and want to offer information, by all means, send us a note. See photos. Will ship USPS with tracking to winning buyer.
