Channel setting is a method whereby stones are held between two bars or strips of metal, called channels.

The sides of the channels are made just a bit narrower than the width of the stone or stones to be set, and then a small notch is cut into each wall. The stone is put in place in those notches, and the metal on top is pushed down, tightening the stone in place.

As with all setting styles, there can be many variations of channel work, bar setting is a variation of channel setting, but with shorter channels running across the ring, rather than down its length.
