The Diva series wine glasses from Schott Zwiesel elegantly showcase every white and red wine with their gently curved bowls and convex-shaped stems. Like a diamond, the patented Tritan crystal glass combines brilliance with extreme durability. This means that Schott Zwiesel glasses are not only dishwasher-safe and scratch-resistant, but they also remain as shiny as the first day even after years of use.
