Mid century jewelry cover the 1940's - 1960's. It is also know as Mid Century Modernism. It is marked by clean lines and bold, abstract geometric shapes. Jewelry created by artists such as sculptor Alexander Calder still sell for hundreds of thousands at auction, and brands like Georg Jensen continue making pieces with the same clean aesthetic. The designs were strong, as the pieces were created from the point of the view of the designer. It is not jewelry to fulfill a function. It is coming from a design perspective. Geometric designs were a key theme in Mid-century Modernism. Most of the jewelry was crafted in silver, partly due to Scandinavian influence (Scandinavian jewelers traditionally have worked in silver) but also the Bauhaus movement, which called on art in all forms to be affordable. And silver, of course, was much more affordable. The 1950s are considered the peak for this kind of design in jewelry. The style remains timeless.
