Definitions

  • the invention relates to a gemstone having a back which tapers to a tip, and a front which is cut in a faceted manner.
  • Gemstones usually have in this case a back which tapers to a tip and is separated from the front by what is known as the girdle.
  • the front can have a table. This design resembling the brilliant cut of a diamond is conventionally referred to in the trade as a chaton.
  • DE 1 079 872 discloses a gemstone which is made of plastic material and has a front which is cut in a faceted manner and tapers to a tip, and a cylindrical back, a metallic mirror coating being applied to the base of the cylinder.
  • AT 006 065 U1 also presents a chaton having a back which tapers to a tip, with which the chaton is applied to a textile backing, for example, and which is mirrored.
  • the object of the invention is to develop the teaching presented in the prior art for imitating the brilliance of a diamond and to provide inexpensive gemstones which imitate the brilliance of a diamond more accurately.
  • a gemstone according to the invention has a back tapering to a tip and a front cut in a faceted manner, regions of the front, i.e. regions lying opposite the tip, being mirrored, allows the back which tapers to a tip to be used as the visible side of the gemstone, in contrast to the prior art.
  • This allows, in contrast to a conventional chaton, the visible face of which forms the front along with the table, novel visual effects to occur resulting on account of the refraction of light at the back tapering to a tip.
  • the facets of the front which are at least partially mirrored, the beams of light are reflected, the facets, in particular the edges between the facets, producing further visually attractive light effects.
  • the front of the gemstone according to the invention which front serves, on account of the mirroring, as the positioning face, itself to have no tip.
  • the gemstone With the front embodied as the positioning face, the gemstone can then be arranged on or in a carrier body.
  • the entire front which is cut in a faceted manner is mirrored, thus further intensifying the above-described effect on account of the reflection of light at the facets, in particular in the region of the edges between the facets.
  • the side facing the viewer is also embodied in a visually elegant manner and can produce attractive visual effects on account of the refraction of light at the facets, in particular at the edges between the facets.
  • the opening angle of the tip of the back may be in a range between 90° and 102°, preferably between 94° and 98°.
  • the front has a table.
  • the front formed by eight faces extending forward from the girdle can end as a table embodied as a regular octagon.
  • the diameter of the table can be between 0.6 times and 0.95 times, preferably between 0.7 times and 0.9 times, the diameter of the gemstone that is provided by the diameter of the face separating the front from the back or that is the diameter of the girdle if such a girdle is present.
  • the front is mirrored, whereby extremely visually attractive effects are produced on account of the reflections caused by the mirroring at the facets and also at the table and at the edges between these faces.
  • the gemstone according to the invention is made of glass, resulting in inexpensive manufacture. Nevertheless, glass stones cut in a faceted manner have a high-quality, very visually attractive appearance.
  • the gemstone according to the invention may also be made of plastic material and be injection-molded, for example.
  • the mirroring is embodied as a reflective layer, it being preferable for this reflective layer to be vapor-deposited onto the corresponding regions.
  • the invention further relates to a composite body with a carrier and at least one gemstone which is arranged in the carrier and is embodied as stated above, the at least one gemstone being arranged with the mirrored region in the carrier.
  • the carrier itself can be made of any desired material.
  • the gemstone is thus arranged with its front, i.e. with the positioning face, in the carrier. It may in this case be preferable for the gemstone to be adhesively bonded to the carrier or stuck onto the carrier.
  • the gemstone it is possible to arrange on the front, in addition to the mirroring which is embodied as a reflective layer, for example, an adhesive layer with which the gemstone is stuck onto the carrier.
  • Possible adhesives used for this purpose are conventional adhesives known per se in the art. These can be cured, for example by increasing the temperature or by applying UV radiation.
  • the composite body has a recess in which the gemstone can be arranged.
  • the recess has in this case a geometrical shape and size corresponding to the front of the gemstone.
  • FIGS. 1 a to 1 d are a plan view, a side view and a view from below of an embodiment of a gemstone according to the invention and also a further side view to illustrate the geometrical sizes;
  • FIGS. 2 a to 2 c are a plan view, a side view and a view from below of a further embodiment of a gemstone according to the invention.
  • FIGS. 3 a to 3 c are a plan view, a side view and a view from below of a further embodiment of a gemstone according to the invention.
  • FIG. 4 is a side view of a further embodiment of a gemstone according to the invention.
  • FIGS. 5 a and 5 b are a plan view and a cross section through a composite body consisting of gemstones according to the invention arranged in a carrier.
  • the gemstone 1 illustrated in FIGS. 1 a to 1 d is made of glass and has a back 2 tapering to a tip 3 , eight planar faces 4 tapering, as is conventional in gemstones sold in the trade under the name “chaton”, from a marginal edge 9 forming a regular polygon to the tip 3 .
  • the planar faces 4 form the facets of the back 2 of the gemstone 1 .
  • a girdle 10 can also be arranged instead of the marginal edge 9 .
  • FIG. 1 b shows that the gemstone 1 according to the invention has a front 5 cut in a faceted manner, eight planar faces 6 extending forward in a beveled manner, starting from the marginal edge 9 , and ending in this case in a planar table 7 embodied as a regular octagon.
  • the front 5 is provided with a mirroring 12 , so that the edges of the front 5 are indicated by broken lines, as these are arranged under this mirroring 12 which is preferably embodied as a reflective layer.
  • the mirroring 12 itself is not explicitly shown.
  • this mirroring 12 is provided by a reflective layer arranged, for example vapor-deposited, on the outer wall of the gemstone 1 .
  • FIG. 1 c is a view from below onto the gemstone 1 according to the invention, showing the table 7 embodied as a regular octagon, the eight planar faces 6 of the front 5 and also the marginal edge 9 between the front 5 and back 2 .
  • FIG. 1 d shows the geometrical sizes of a gemstone 1 according to the invention.
  • the overall height of the gemstone 1 is obtained from the distance between the tip 3 and table 7 , this height being measured perpendicularly onto the table 7 .
  • the diameter D S of the gemstone 1 is measured perpendicularly to this height, i.e. parallel to the table 7 .
  • the plane of this diameter D S separates the front 5 from the back 2 , the back 2 having a height H R and the front 5 having a height H V .
  • the table 7 has a diameter D T .
  • the back 2 of the gemstone 1 has at the tip 3 an opening angle ⁇ .
  • the angles of the lateral faces 4 and 6 respectively are measured with respect to the plane containing the diameter D S .
  • the angle of the lateral faces 4 of the back 2 is in this case denoted by ⁇ , whereas the angle of the lateral faces 6 of the front 5 is denoted by ⁇ .
  • FIGS. 2 a to 2 c show a further embodiment of a gemstone 1 according to the invention, the only difference from the gemstone of FIG. 1 a to 1 d consisting in the fact that the tip 3 is rounded off or flattened to form a culet 8 .
  • the faces 6 of the front which is cut in a faceted manner 5 and also the table 7 are mirrored, so that the edges arranged there are arranged under this mirroring coating 12 and are therefore indicated by broken lines.
  • FIGS. 3 a to 3 c show a further embodiment, the only difference from the gemstone 1 illustrated in FIGS. 1 a to 1 d consisting in the fact that a substantially circular girdle 10 , which separates the back 2 from the front 5 , is arranged instead of a marginal edge 9 .
