Vintage Juliana Butterfly Brooch

After some research and after a kind person let me know this may be a Juliana, I have spent the last few days researching online and going through books and believe this may be a Juliana brooch. This has prong set marquise stones, curled wire antenna. Please see pictures for more details. If you have any questions or would like more details, please do not hesitate to ask. Non smoking home. We do have a dog. I will drop off for shipping next day, Monday through Saturday, in the morning. If you purchase on Saturday or Sunday, I will ship on Monday (If the post office is closed for a holiday, I will ship the following day). I welcome all reasonable offers, I will either accept or I will respond back with my best offer. Thank you for looking!
