You may have heard of Alexander Calder, an American artist. He created a lot of art work including some famous 'mobiles'. What you may not know is that he also produced some unusual jewellery. During his life he created 1,800 pieces of brass, silver and gold body adornments, including necklaces, bracelets, tiaras, and brooches. Some of his work is held at the Calder Foundation, and the Metropolitan Museum of Art http://www.metmuseum.org/ dedicated an exhibition of jewellery to his work in early 2009. One of the motifs he used a lot was a fish which became a design for his brooches.
