The Diva series wine glasses from Schott Zwiesel showcase every white and red wine in a stylish and elegant manner with their gently curved bowls and convex-shaped stems. Much like a diamond, the patented Tritan crystal glass combines brilliance with extreme durability. As a result, Schott Zwiesel glasses are not only dishwasher and scratch-resistant, but they also remain as brilliant as the first day even after years of use.
