Looking for a certain wine glass

[hotwine]

Welcome, LA. That sounds like a piece of Riedel (pronounced Ree'-dul) stemware, arguably the finest wine crystal in the world. You can look at the many wine glasses they make in their Austrian factories at www.riedelcrystlal.com. You may not be able to recognize your stemware from their website illustrations; suggest you take an intact glass from the set to the best wine & spirits retailer in your area, and ask for assistance in identifying it, and in obtaining a replacement.
But - if the glass is merely separated into major components (bowl, stem and base), you might be able to glue them back together.....
Good luck.
