This listing is for an etched crystal wine glass. 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. There are just a few differences. This glass has a smooth rather than a bulbed stem. It also has a more bulbous bowl. The flowers in the Danube pattern are completely frosted whereas the flowers in this glass 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 glass is 6" x 4-1/4".
