Recently DesignBoom was selling some of 22designstudio's rings, and they sold out in a flash. I was lucky enough to get one, and I've got to say I love it.  The rings are made of Stainless and concrete, and the concrete feels surprisingly smooth.

"Drawn freehand by the designer, the circular frame of this ring acts as the beginning of a dialog between the designer and the person wearing it. The circular design creates ever-lasting space for communication and interaction between creator and receiver, designer and customer."
