These aren't what I usually think of when I think of cocktail rings but these have more of a purpose than just to dazzle bystanders. The FingerFood Rings from Fred & Friends are packs of 12 reusable plates that fit on your finger and hold small hors d'ouevres. Definitely a risky idea for those who talk with their hands or who have an interest in eating more than one canape at a time but I can see them perhaps serving a function similar to the white spoons that often hold an amuse bouche. They could look quite cute all topped and arranged on a tray.
