1975 Early Prototype Tiffany Bone Cuff

Peretti’s arrival at Tiffany & Co. in 1974 heralded a never-before-seen aesthetic. This sensuous, rare bracelet is dated 1975. It is one of her earliest creations and served as the prototype for the iconic "Bone Cuff".
Designed with a confident, sexy fluidity. Organic curvy openings on each side reveal the bones of the wrist. This means the bracelet can be worn on either wrist and still showcase the bones on the wrist. Her later version is limited by their design to either the only right or left wrist for wearing.

Referred to as simply "Cuff Bracelet", the design was first offered in the Tiffany & Co. Blue Book 1976-1977 Collection. (Please see informational image.) Wear commensurate with age and use.
