Definitions

  • the invention relates to a setting for a gemstone, with a holding body or jewelry part, in which / the gem is inserted, for which purpose a hole is provided in the holding body / jewelry part, the entry cross section of which corresponds at least to the cross section of the gemstone to be grasped, and why in a recess is made in the wall of the bore for receiving an elastic holding member which at least partially surrounds the gem and holds it in the bore.
  • depressions are made in the circumferential area of the gem, which, in conjunction with the elastic holding member, serve to securely fix the gem in the bore.
  • these depressions in the peripheral area require a high level of technological effort, in particular because of the hardness and sensitivity of the gemstone.
  • a special area of application for such a setting is the mounting of a gem in a watch glass.
  • the object of the invention is to simplify the known version in its manufacture by reducing the number of operations required and to make it less expensive.
  • this object is achieved in that the bore has a support area for the gemstone with respect to its inlet cross-section, that the depression is made in the wall of the bore between the area of the maximum cross-section of the gemstone and the inlet cross-section of the bore, and in that the elastic holding member is designed in such a way that its sections abutting the gem are prestressed inwards so that they generate a holding force on the gem in the axis of the bore in the direction of its bearing area.
  • the bottom of a blind hole is used as a support area, so that the elastic holding member only has to exert a force on the gem in the direction of the bottom of the blind hole in order to hold it there.
  • the holder is made of transparent material; Regardless of the material of the holder, a peripheral edge, for example, can also suffice as the support area, which largely leaves the gem free.
  • This configuration makes it possible to completely dispense with indentations in the circumferential area of the gemstone, which represents a considerable saving in labor and technology, since this step in the known version must be carried out with particular precision and care.
  • the holding member is designed as an n-angular wire with outwardly bent, inwardly resilient legs, the corners of which engage in the recess in the form of an annular groove in the wall of the bore.
  • the inward spring action of such a wire in cooperation with the downwardly tapering circumferential surfaces of the gemstone, creates the desired pressing action on the gemstone in the direction of the bearing area of the bore and thus a secure mounting.
  • a variant according to the invention with a continuous support area is particularly advantageous if the holding body is a watch glass, since there are no sealing problems here, since the closed surface of the watch glass points upward.
  • the bottom of such a blind bore is convex or concave; In this way, optical effects can be achieved in particular, which can further enhance the effect of the gemstone.
  • a blind bore 12 (FIG. 1) is made in the holding body 11, for example a watch glass, from the underside in such a way that a gem 10 can be inserted through the opening 12A of the bore 12 to the bottom 12B thereof as a support area.
  • an annular groove is made as a recess 13, namely at a height X1, which is below the height X2 of the largest cross-sectional area of the gemstone 10 used.
  • a platinum-iridium ring which can be expanded elastically in the plane II-II is inserted as a holding member 14, in such a way that its two corners 14C, 14D engage in the annular groove 13 and its sections 14A, 14B to the downward towards Bear in the direction of the opening 12A of the bore tapering side surfaces of the gem. Due to the inherent clamping force of this snap ring, the sections 14A, 14B bear against these side surfaces of the gemstone, as a result of which the inward forces acting in the plane II-II (arrows S in FIG. 2) in a direction towards the bottom 12B of the bore 12 directional pressing force F is formed, which presses the gemstone 10 on the floor 12B.
  • the second exemplary embodiment (FIG. 3) is structurally essentially the same as the first; however, a circumferential bead 12C at the output cross section 12D of the bore 12 serves as the support area, which acts as an abutment against the force of the elastic holding member 14 due to the narrowing of its cross section.
  • This variant gives a clear view of the top of the gem.
  • the snap ring is designed with two corners, but it is also readily possible to provide a snap ring with several corners in adaptation to the shape of the gemstone 10, for example in the form of a trichoid, i.e. a triangle with legs bent outward.
  • the snap ring does not necessarily have to be closed, a bow-like shape is also conceivable, provided that it is only ensured that the forces exerted by the legs on the gemstone 10 ensure an adequate press fit in the bore 12.
