Definitions

  • the invention relates to a process for obtaining, on a metallic mass, phenomena of local glosses imitating those of a cut diamond.
  • FIG. 1 The drawing of Figure 1 is that of a daisy whose petals thus hollowed out as visible in Figure 2 converge towards a central point K located on the lateral surface of the band of the alliance.
  • the diamond setting of this cutter has a triangular profile.
  • a notch (Fig. 6) is established in this projection S1, by means of a cutter 02 also with a triangular profile (of angle 120 °), rotating around a horizontal axis 0 placed vertically from the top of the SI cone.
  • the star visible in Figure 3 is obtained by making four identical notches crossing at 45 °.
  • this circular projection S1 if it were of another profile, for example spherical, in a drop of tallow, or with a broken generatrix, would lead to notches drawing decorations other than a star.
  • the mandrel M can be moved angularly along its horizontal axis to multiply the decorations around the perimeter of the jewel which can be a ring ring, an alliance, a "creole” earring and even a bracelet.
