This bat won't fly around your head or echolocate. He's small and tidy and just the tiniest bit creepy-cute. Mounted on a solid split band style, he wraps around your finger about an inch, and is just half an inch wide. Total width with bands: 13mm, tapering to a comfortable 4mm on the bottom of the shank. Shown here blackened and set with a genuine oval amethyst, which measures 7 x 5mm. 6.4 grams of sterling silver.
