Definitions

  • the invention relates to a faceted, refractive and light-reflecting gem.
  • Such gemstones arose from imitation of chandelier glasses, were previously made of glass and later made of transparent plastic.
  • Chandelier glasses have iridescent coatings that arise when, for example, dissolved silver-sulfur resinates are added to glass and burned with the addition of certain salts. These iridescent coatings are semi-transparent mirrors that enhance the refractive effect on the surface of the glasses, at the interface between glass and air.
  • the chandelier glasses are provided with a large number of surfaces at an angle to each other, similar to a brilliant cut.
  • a reflex intensification is achieved in that the back of the gemstone, which also has planar surfaces at an angle to one another, is provided with a reflective metal coating.
  • the invention has for its object to provide such a gem that reflects light rays hitting the gem as strongly as possible, largely bundled and also partially refracted. This is achieved according to the invention by means of two transparent half-shells which are faceted, each of which is facetted in the inner curvature and / or on the outer curvature.
  • this metal covering is made very thin as a semi-transparent mirror, the light rays can penetrate through the metal covering into the gem. It is thus also possible to facet both half-shell inner curvatures and to provide them with a semitransparent reflecting metal coating, so that this gemstone reflects, breaks and transmits light from both the back and the front. This makes it possible, for example, to produce very appealing, glittering earrings.
  • the facets of the inside and outside bulges are designed in the same way and mutually offset by half a partial step. This results in a large number of prismatic surfaces with the corresponding light refraction. The same then applies if the facets of réellewölbun- g of the half shells s turn identical and gegenseiig to each fourth partial step are offset.
  • the half-shells are expediently curved in an aspherical manner.
  • the half-shells are made of the same type and made of transparent plastic.
  • the injection-molded from transparent plastic half-shell 1 is bun both the inner buckle 2, as well as at the discoursewöl- g 3 faceted 4.
  • the edge 5 of the half-shell 1 is flat and perpendicular to the axis of the half-shell 1. This makes it readily possible to provide two Glue half-shells 1 to each other so that the entire gem is created.
  • One of the inner curvatures 2 can be provided with a reflective metal covering. If this metal covering is designed as a semitransparent mirror, both inner curvatures can also carry such a covering.
