An apparatus for use in forming a finish on a jewelry band has a base, a chassis rotatably mounted to the base and a mandrel rotatably mounted to the chassis. The mandrel is operable to engage the blank jewelry band on which the finish is to be formed. The apparatus further includes means allowing the chassis to be secured in position relative to the base and means allowing the mandrel to be secured relative to the chassis. The finish is produced by positioning a forming tool having a predetermined front cross section against the blank jewelry band and striking the forming tool, forming an indent in the band corresponding to the shape of the forming tool. The relative independence of the mandrel, chassis and base allows the band to be positioned at an ideal angle for striking.
