This example can be worn as a triple clip brooch, the scroll terminals detaching to be worn as clips or attaching to a bangle, effectively creating four different jewels, justifying its own luxury with function. This archetypal jewel is a wonderful example ofbined technical skill and the creative flair required for this period.For design drawings of similar examples by Cartier, see Rudoe, J., 'Cartier 1900-1939' (London, 1997), p. 330-331.The firm of Carlo Illario e Fratelli was founded in 1920 and produced jewels for Bulgari throughout the mid-20th century, including their iconic Serpenti watch bracelets, a favourite design of Hollywood actress, Elizabeth Taylor.
