Molly Perrin / Brian Lee Dreesman

These are rings Carrie Mathison would be proud to wear. In her "Gleam" collection, UK jeweller Molly Perrin explores keyholes and spyholes, equipping her rings with riveted lids that "swivel to reveal a hidden compartment or a lens."

Visit her site for more work inspired by furniture components, such as these rings "based on the mechanisms used in drawer handles and to hang frames on the wall."
