This listing is for an etched crystal water goblet.  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 floral and stem patterns it is Col1.  There are just a few differences. This glass has a bulbous rather than a bulbed stem.  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 7-3/4" x 3-1/4".
