B.zero1 or Possession

Stacked bands define both rings, but only Possession lets them move. B.zero1, launched by Bulgari in 1999, coils a spiral between two rims engraved with the house name, its profile taken from the tiers of the Colosseum, in one to five turns. Possession, Piaget's ring within a ring from 1990, carries an outer band that spins freely, later chased with the Decor Palace texture of the house's watches or set with malachite and turquoise. The spiral is built to be looked at, the spinning band to be played with.
