The great American sculptor Alexander Calder made the most desirable and interesting jewellery. It is unmistakably recognisable as his work, yet it is also obviously fine jewellery. Meaning, to my mind, sometimes art jewellery can look too "forced" and clunky; it wears you rather than the other way round. I love these pieces - they are so stylish and fun!
Above is a brooch, two hair combs, a necklace, a hair pin, a tiara and a ring. He was as prolific in jewellery making as he was at making mobiles and stabiles. If you'd like to see more of his jewellery designs, here is a good place to start: Calder Foundation.
