Hi Cat,
I hope pics shows better that the bottom is satin finished (2 pics same area, one sharper than the other). In the end, it's blown bubbles, satin finish bottom, rough pontiff cut. I do believe it was made sometime ago and that it's Italian and perhaps Murano. The color is more cranberry than purple (light reflections merged in sections, interfered with getting cranberry color). Heavy for a small vase - 3 lbs - 11" highest point - 5 1/2" widest point. Glass is thick.
You have been soooo helpful. And I learn, and learn, and learn. Thank you very much. If you any further conclusions, would love to hear.
Best regards,
Carole
