Lustrousstone and stew2u2, I thank you for your input. Greatly appreciated. I read about the 'Rare Optics' at retro-art web site where they stated: Giant Brandy Snifter Vase with Rare Spiral Optic in Moss Black
Comes from mid-20th Century Italy. Especially popular form made by many glass artists. This one was made by a pro. It has a spiral optic that is mesmersizing. Most of the oversized snifter vases had various optic decors, but a beautiful spiral twist like this is rarely seen.
Thinking on it a bit more concentrated, my Mother had other vases that were not kept in the cabinet, it was always just those 3 and I don't recall her ever using them. My brother and I knew that cabinet was off limits, I can recall 'Don't play around the cabinet, please! Even when we had our house cleaning chores to do, it was Mom that always dusted the cabinet. I just never really gave it much thought up until now. One other article that I inheirited that was in the cabinet, although not made of glass, is this Gold Gilted? Statue, if thats the correct wording? I recently saw a statue of great resemblance and the write up said it was from France, 1800's circa. Please see jpg. One is with the flash on and the other without. The lines are a slight green patina that has formed.
I can't remember just what else was in that cabinet. I think maybe my Brother maight have whatever else there was. I think I will read more on Itallian Glass. And Stew2u2, I see the raised G. I hadn't noticed it before. Thank you!
