Marla Aaron - Trundle Lock 18-Karat Gold Ring - 6

Marla Aaron's ring is engineered with a tiny roller, inspired by the wheels of the 16th century - it's hinged at one side to create a little movement. Cast from 18-karat gold, it has slender, flat sides and is subtly scribed with the label's initials on the inside of the band. The barrel is finished with an intricate hand-engraved floral motif, so no two are exactly the same.
