His wife, Louisa James, was the first lucky one to receive a piece of his work: a token of love that came in the form of a hammered brass bracelet. Although more well-known for his abstract mobile sculptures, American artist Alexander Calder made more than 1,800 earrings, bracelets, necklaces and brooches during his lifetime. Copper, brass, silver, glass, wood, leather or ceramics: his avant-garde, unconventional jewelry was described as ‘unwearable art’. Although the artistic value of his creations was beyond question, Calder considered jewelry-making as a hobby and only made pieces for his family and friends. Luckily, his friends were prominent people in the art world like Peggy Guggenheim, Georgia O'Keeffe, Madame Miró, Madame Duchamp and Madame Chagall, who certainly recognized and appreciated high-caliber artwork when they saw it.
