The heyday of cut steel jewelry was in the late 18th century and is considered “secondary jewelry” because of it’s bold, playful and modern aesthetic. It is comprised of tiny studs or nails mounted into a base plate. It was a time consuming endeavor as the studs or nails were individually faceted and polished. They were then riveted one at a time through tiny holes to a base plate. They were fastened to the base plate in the best way to catch the candlelight to emulate the brilliance of diamonds. When you find pieces that survive today that are in good condition, it is remarkable that they haven’t rusted after all of these years.
