The Bone cuff by Elsa Peretti for Tiffany & Co. is one of the New York jeweller's most sought-after designs. The sculptural lines of the cuff demonstrates the Italian designer's mantra, "style is to be simple", taking objects back to their most simple form and displaying them in their most pure state. This Bone cuff is crafted from copper with a charcoal-coloured ruthenium coating, giving the cuff a wonderful metallic sheen that complements the fluid lines. Testimony to the iconic status of the Elsa Peretti collection for Tiffany & Co. Bone cuff, it was incorporated into the British Museum's permanent 20th century collection in 2009.
