In Bead Setting a seat is cut for the stone in the object, small amounts of metal are then raised out of the surrounding metal with an engraving tool, and pushed over the stone, to act as claws. These claws are then tightened down onto the stone with a small tool with a concave end. By rotating this tool over the claw, the claw is formed into a small ball or bead. The tool is called a beading tool. Wal.
