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.
Claims7
A method of making set ring comprising the steps of:
- (a) forming a ring member having an outer cylindrical surface;
- (b) forming a groove in the outer cylindrical surface of the ring mounting member, the groove extending at least partially around the circumference of the ring mounting member, and the groove defining a pair of upstanding rims, each having an upper end surface;
- (c) machining a plurality of equidistantly spaced depressions in the bottom of the groove;
- (d) drilling a setting hole centrally in each depression;
- (e) placing a gem in each of the setting holes to obtain a desired orientation of the gems;
- (f) applying a sheet of adhesive material to the upper end surfaces of the pair of upstanding rims and to a crown portion of the gems to the thereby hold the gems in place;
- (g) rotating the ring mounting member while pressing a roller against the pair of rims, thereby toeing the rims inwardly into engagement with the gems;
- (h) removing the sheet of adhesive material;
- and
- (i) polishing the ring mounting member to form a desired final shape.
