Jen Brill, Sally Singer, Bonnie Morrison, and Fe Fendi joined 22-year-old Fendi family heiress Delfina Delettrez Fendi for the first stateside presentation of her Anatomik jewelry collection at Opening Ceremony last Thursday.

Greatly inspired by Delettrez Fendi's obsession with the anatomy of the human body, the jewelry collection features a cuff shaped like vampire teeth, skull cabochon rings, and diamond encrusted pinky fingers. “I have always been fascinated with the body; I don’t know why,” Delettrez Fendi said. “From the mouth to the feet, it’s very inspiring to me — especially the hands.”

Silver skeleton shaped slave bracelets that mimicked the bone structure of the hand were among the most interesting (and fun to try on) for party-goers. “You have to play with the jewels, Fendi explained. "Now people don’t want to have jewels that are shiny and don’t want to have the big diamonds. They want to have the jewels that seem fake! But you just know it’s real. It seems like a toy.”

The collection, which retails from $450 to $65,000, is available at Opening Ceremony boutiques in New York and Los Angeles.
