George Higby is a licensed appraiser, notable youtube content creator, and well seasoned antiques dealer. He has been in the business for decades and has confirmed that it is indeed Vic torian era Opaline, likely Bohemian (Czech) in origin. He goes on to explain that it was likely one of a pair used as mantle garniture.
It is truly a wonder that it has survived nearly 200 years in this condition and will likely be the only one I'll ever find! A wonderfully unique and high end piece for any serious uranium or bohemian glass collector. Will double box, insure for full value, and require signature confirmation.
