Claude Montana was a fashion designer who was active from the 1970s to the 1990s. He is known for his innovative and sculptural designs that often incorporated unconventional materials and bold silhouettes. While he is best known for his fashion designs, he also created a line of jewelry in the 1980s and 1990s that was characterized by its bold, geometric shapes and use of metallic finishes. Montana's jewelry was often designed to complement his clothing collections, and his use of metal and sculptural shapes reflected his interest in industrial design.
