Alexander Calder
Between 1920 and 1950, the greatest number of pieces of jewelry were characterized by the rich metal and precious stones employed in their manufacture, in addition to an extremely professional technique and a justness handwork.
It is logical that Calder became interested in sculpture and jewelry since that both entangle movement and three dimensions.
