Works by famous artists bring high prices as examples of great design. A 1940s twisted silver wire necklace by Alexander Calder (1898-1976) sold for $267,750 at a Christie's sale in September 2013. Calder, famous for his mobiles, created his own style of jewelry and never soldered pieces of metal. Instead, he bent or riveted pieces together.
