Measures approximately 2" (5.1 cm) in width across the center, and 13/16" (2.1 cm) in width at the ends. The stone in its setting measures approximately 2" (5.1 cm) by 1-3/8" (3.5 cm). The stone moves ever so slightly in the setting but is completely secure, and, as seen in the photo, the design is imperfect on one side of the band.
