This listing is for an etched crystal iced tea/water tumbler. From the research I've done, the closest match I can find is the brand Colony, style either Danube or Col1. I believe based on the leaf patterns it is Danube. The only difference is the stem shape and the flowers. This tumbler has a bulbous rather than a bulbed stem. The flowers in the Danube pattern are completely frosted whereas the flowers in this tumbler have an open center. If you are buying this as a replacement piece, please check before you purchase. Please also see the video for a better idea of what I'm referring to.
The glass is healthy with no chips, cracks, or hard water marks from being run through a dish washer. There are some air bubbles consistent with hand blown glass. The tumbler is 6" x 3 1/4".
