In the 80s, I bought 3 Tiffany 'bone' cuffs from the private collection of a discriminating high-end antique dealer. These iconic pieces were designed by Elsa Peretti in the 70s, when she first came to Tiffany and were at the time EXTREMELY avante-garde. Tiffany originally offered the biomorphic cuffs in 3 widths--small, about an inch and a half wide, medium at two and a half inches, and the RARE large cuff--wide enough to fit well up the forearm. All three were available for either the right or left arm. The large cuff was very pricey, and a more demanding design than the smaller. It is out of production and impossible to find.
