ABSTRACT:
A tool and method for cutting a seat in a setting of jewelry for receiving a gemstone having a crown, a girdle, and a pavilion. The tool has a cylindrical shank portion having a smooth outer surface and a bur cutting portion attached to said shank portion at one end for conjoint rotation therewith. The bur cutting portion has cutting surfaces disposed for rotation about a longitudinal axis of the shank portion and includes first and second generally conical cutting surfaces and a generally cylindrical cutting surface located between the conical cutting surfaces. The cutting surfaces are constructed to cut into the setting of the jewelry upon rotation of the tool about the longitudinal axis of the shank portion to form the seat in the setting. The notch that is cut has at least three distinct surfaces, each being complementary to a corresponding profile surface of the gemstone.
