This vase is 12" (30 cm) high and about 7.5" widest diameter. Bottom is concave ground and polished smooth. It has a Corning Museum of Glass UPC label on the bottom and is estimated to have been made 1980-2000. No other label has survived and it is not marked. CMoG sold/sells a wide variety of glassware in their museum store from all over the world. Not sure if this was true between 1980 and 2000. Any thoughts on the origins and maker of this vase?
