These unique fossil stones are made with concrete, copper and sterling silver. Each one inch, half dome casting contains a shell, pebble or a smaller concrete sphere embedded within its center. Once the concrete is dry, I scratch into it and treat it with metallic paints and chemical patinas to create the antiqued, rusty and greenish/blue surface. I work into each stone with oil paint, bronze powder, and seal them with a matte varnish. I solder a sterling silver tube bail to a 1″ copper O ring to create the base. The stones are then epoxied to the copper base, which allows the raw concrete to be visible from the back.  They hang from an 16″ or 18″ 2mm black rubber cord with a sterling silver clasp. They are one of a kind!
