Margaret De Patta was an American jewelry designer and artist who worked primarily in the mid-20th century. She was known for her modernist designs that incorporated geometric shapes and abstract forms. De Patta was one of the pioneers of the American studio jewelry movement, which emphasized the use of traditional techniques and the handmade nature of jewelry. She often worked with non-traditional materials, such as plastic and aluminum, and was interested in the way that light interacted with her designs. De Patta's work has been exhibited in museums and galleries around the world and is highly regarded for its artistic and technical innovation.
