ABSTRACT:
A channel set ring is provided with a plurality of substantially equidistantly spaced depressions formed in the bottom of a U-shaped groove. Setting holes are formed centrally in each of the plurality of depressions. Once the gems to be set are placed with their pavilions in the setting holes, a piece of tape is used to hold the gems in place while the ring is rotated on a lathe. The upstanding rims formed by the groove are turned with a roller while the ring is rotated on the lathe. After turning the rims, the tape is removed.
