The Lismore Arcus Tumbler, Set of 2 from Waterford combines traditional diamond cuts with arch motifs inspired by castle architecture for the pattern's seventieth anniversary. This pair features cylindrical proportions that work across various beverages, with artisans hand-cutting both geometric patterns to create textural variation. The alternating motifs reference Miroslav Havel's original vision while updating the vocabulary through structural elements. A substantial crystal weight provides comfortable handling, as faceted surfaces multiply light refraction, bridging the collection's heritage with contemporary drinking needs through an evolved design language.
