Description

Die Erfindung betrifft einen Schmuckstein mit einem Chatonschliff.The invention relates to a gemstone with a chaton.

Zur Verbesserung der Brillanz und weiterer optischen Eigenschaften eines facettiert geschliffenen Schmucksteins, wurden im Laufe der Zeit verschiedenste Arten von Schliffen entwickelt, die sich einerseits durch die Anzahl der Facetten und andererseits durch die gegenseitigen geometrischen Lagebeziehungen der Facetten unterscheiden.To improve the brilliance and other optical properties of a faceted cut gemstone, over the course of time various types of cuts have been developed, which differ on the one hand by the number of facets and on the other by the mutual geometric positional relationships of the facets.

Insbesondere für Chatonbereich hat sich der sogenannte Oktant- oder Xilionschliff (zB Swarovski-Steine A1200 und A1028) in der Vergangenheit am Markt etabliert, da sich diese als ästhetisch und gut schleifbar herausgestellt haben.Especially for Chatonbereich has the so-called octant or Xilionschliff (eg Swarovski stones A1200 and A1028) established in the past in the market, as these have proven to be aesthetically pleasing and easy.

Wichtige Parameter für die Beurteilung eines Schmucksteins sind das so genannte "Fire" (Feuer) und "Light Return" (Lichtausbeute), das auf zahllosen inneren Lichtreflexionen beruht. Diese Lichtreflexionen werden an den einzelnen Facetten hervorgerufen, die in speziellen, den jeweiligen Schliff charakterisierenden Winkelverhältnissen zueinander stehen. Der Schliff und das Material eines Schmucksteins sind somit maßgeblich für das erzeugte "Fire" und "Light Return",Important parameters for the assessment of a gemstone are the so-called "Fire" and "Light Return", which is based on innumerable internal light reflections. These light reflections are caused by the individual facets, which stand in special angular relationships characterizing the respective cut. The cut and the material of a gemstone are therefore crucial for the generated "Fire" and "Light Return",

Der "Light Return"- Wert gibt an, wie viel Licht, das aus einem vordefinierten Raumwinkelbereich auf den Schmuckstein auftrifft, in einem relativ engen (Öffnungswinkel 3°) gerichteten Raumwinkelbereich auf den Betrachter im Wesentlichen entlang der Symmetrieachse des Steines zurückfällt.The "light return" value indicates how much light that strikes the gemstone from a predefined solid angle range falls back onto the observer essentially along the axis of symmetry of the stone in a relatively narrow (opening angle 3 °) directed solid angle range.

Ein weiteres wichtiges Merkmal zur Beurteilung der Brillanz eines Schmucksteines ist das "Fire". Als "Fire" bezeichnet man die Eigenschaft eines Schmucksteins, das einfallende weiße Licht in seine spektralen Anteile zu zerlegen. Die Ausprägung dieser Eigenschaft ist sowohl vom Material (Dispersion) als auch vom Schliff abhängig.Another important feature to assess the brilliance of a gemstone is the "Fire". The term "fire" refers to the property of a gemstone to break up the incoming white light into its spectral components. The expression of this property depends on both the material (dispersion) and the cut.

Ein Schmuckstein mit einem Chatonschliff weist eine Krone, auch Oberteil genannt, mit einer definierten Anzahl an seitlichen Facetten und einer mittleren ebenen Tafel, sowie ein Pavillon, auch Unterteil genannt, mit einer definierte Anzahl an Facetten, auf. Das der Tafel gegenüber liegende Ende des Schmucksteins kann als Spitze oder als abgerundete Spitze in Form einer so genannten Kalette ausgebildet sein. Zwischen Ober- und Unterteil kann eine so genannte Rondiste (Umfangsrand) angeordnet sein. Der Schmucksteins kann symmetrisch oder asymmetrisch geschliffen sein.A gemstone with a chaton section has a crown, also called upper part, with a defined number of lateral facets and a middle plane board, as well as a pavilion, also called lower part, with a defined number of facets on. The opposite of the table opposite end of the gem can be used as a tip or as be formed rounded tip in the form of a so-called caliber. Between the upper and lower part of a so-called Rondiste (peripheral edge) can be arranged. The gemstone can be ground symmetrically or asymmetrically.

Aufgabe der Erfindung ist es, den ästhetischen Eindruck eines Schmucksteins mit einem Chatonschliff durch Optimierung von optischen Parametern, insbesondere von "Fire" und "Light Return", weiter zu verbessern.The object of the invention is to further improve the aesthetic impression of a gemstone with a chaton section by optimizing optical parameters, in particular "fire" and "light return".

Dies wird durch einen Schmuckstein mit den Merkmalen des Anspruchs 1 gelöst.This is achieved by a gem with the features of claim 1.

Indem der Schmuckstein einen Chatonschliff aufweist, bei dem der Kronenwinkel (α) zwischen 40,5° und 42,5° beträgt, hat sich überraschend eine besonders hohe Lichtausbeute ("Light Return") bei gleichzeitig hohem "Feuer" ergeben. Die Szintillation (Funkeln des bewegten Schmucksteines) und die Brillianz des Schmucksteins kommen besonders gut zur Gettung.By the gemstone has a chaton section, in which the crown angle (α) is between 40.5 ° and 42.5 °, surprisingly, a particularly high light output ("Light Return") resulted in high "fire". The scintillation (sparkling of the moving gemstone) and the brilliance of the gemstone are particularly good for gettung.

Der Kronenwinkel ist jener Winkel, der sich bei einer Seitenansicht des Schmucksteins zwischen der seitlichen Begrenzungslinie der Krone und der Rondistenebene ergibt, wobei diese Begrenzungslinie sich durch eine Orthogonalprojektion einer Kronenfacette auf eine Ebene ergibt, die die Längsachse des Schmucksteins enthält.The crown angle is that angle which results in a side view of the gemstone between the lateral boundary line of the crown and the rondistine plane, this boundary line resulting from an orthogonal projection of a crown facet on a plane containing the longitudinal axis of the gemstone.

Die Rondistenebene ist jene Ebene, die parallel zur Tafel angeordnet ist und in der der Schmuckstein die größte Querschnittsausdehnung aufweist. Die Rondistenebene ist senkrecht zur Längsrichtung des Schmucksteins ausgerichtet.The Rondistenebene is that level, which is arranged parallel to the board and in which the gemstone has the largest cross-sectional dimension. The Rondistenebene is aligned perpendicular to the longitudinal direction of the gem.

Der "Light Return" (die Lichtausbeute) und das "Fire" (Feuer) können gemessen werden, beispielsweise wie es weiter unten anhand der Fig 5 und Fig 6 beschrieben ist. Statt einer tatsächlichen Messung kann die Messung anhand der Geometrie und des Materials des Schmucksteins auch rechnerisch simuliert werden.The "light return" and the "fire" can be measured, for example as shown below FIG. 5 and FIG is described. Instead of an actual measurement, the measurement can also be simulated mathematically on the basis of the geometry and the material of the gemstone.

Weitere vorteilhafte Ausführungen der Erfindung der Erfindung sind in den abhängigen Ansprüchen definiert.Further advantageous embodiments of the invention of the invention are defined in the dependent claims.

Es hat sich herausgestellt, dass besonders bevorzugte Kronenwinkelbereiche (α) zwischen 41,75° und 42,25° liegen. Ganz besonders bevorzugt ist der Kronenwinkel (α) bei 41,95°.It has been found that particularly preferred crown angle ranges (α) are between 41.75 ° and 42.25 °. Very particularly preferred is the crown angle (α) at 41.95 °.

In einer bevorzugten Ausführungsform der Erfindung beträgt der Pavillonwinkel (β) zwischen 39,5° und 41,5°, vorzugsweise zwischen 40,5° und 41,0° und ganz bevorzugt 40,73°.In a preferred embodiment of the invention, the gazebo angle (β) is between 39.5 ° and 41.5 °, preferably between 40.5 ° and 41.0 °, and most preferably 40.73 °.

Der Pavillonwinkel ist jener Winkel, der sich bei einer Seitenansicht des Schmucksteins zwischen der seitlichen Begrenzungslinie des Pavillons und der Rondistenebene ergibt, wobei diese Begrenzungslinie sich durch eine Orthogonalprojektion einer Pavillonfacette auf eine Ebene ergibt, die die Längsachse des Schmucksteins enthält.The gazebo angle is that angle which results in a side view of the gemstone between the lateral boundary line of the gazebo and the girdle plane, this gauging line resulting from an orthogonal projection of a gazebo facet on a plane containing the longitudinal axis of the gemstone.

Obgleich der erfindungsgemäße Schmuckstein bevorzugt aus einem Glas hergestellt sein kann, ist auch ein Schmuckstein aus natürlichen oder synthetischen Edel- oder Halbedelstein oder Kunststoff mit dem erfindungsgemäßen Chatonschliff möglich.Although the gemstone according to the invention may preferably be made of a glass, a gemstone of natural or synthetic precious or semi-precious stone or plastic with the Chaton cut is also possible.

Die Krone des Schmucksteins, die auch als Oberteil bekannt ist, weist eine Tafel auf, an die acht Kronenfacetten mit jeweils einer Breitseite angrenzen. In einer Ausführungsform der Erfindung weisen diese Kronenfacetten zur Rondistenebene einen Winkel zwischen 33,5° und 35,5° (vorzugsweise zwischen 34,25° und 34,75° und ganz bevorzugt bei 34,52) auf.The crown of the gemstone, which is also known as the upper part, has a board, bordered by the eight crown facets, each with a broadside. In one embodiment of the invention, these crown facets have an angle of between 33.5 ° and 35.5 ° to the rondist plane (preferably between 34.25 ° and 34.75 ° and most preferably 34.52).

Darüber hinaus weist die Krone acht weitere Kronenfacetten auf, die jeweils mit einer Breitseite an die Rondiste angrenzen. In einer Ausführungsform der Erfindung beträgt der Winkel zwischen diesen Kronenfacetten und der Rondistenebene zwischen 40,5° und 42,5° (vorzugsweise zwischen 41,75° und 42,25° und ganz bevorzugt bei 41,95"), Die Orthogonalprojektion der letzt genannten Kronenfacetten ergibt den Kronenwinkel.In addition, the crown has eight other crown facets, each with a broadside adjacent to the Rondiste. In one embodiment of the invention, the angle between these crown facets and the rondist plane is between 40.5 ° and 42.5 ° (preferably between 41.75 ° and 42.25 ° and most preferably at 41.95 "), the orthogonal projection being the last one mentioned crown facets gives the crown angle.

Der Pavillon, der auch als Unterteil bekannt ist, weist mindestens 16 Pavillonfacetten auf, die in Form einer Spitze oder einer Kalette am der Tafel gegenüberliegenden Ende zusammen geführt sind. Dabei haben in einer Ausführungsform acht Pavillonfacetten eine Spitze, die in Richtung zur Rondiste angeordnet ist, während 8 Pavillonfacetten eine Breitseite aufweisen, die an die Rondiste angrenzt. Das der Breitseite gegenüber liegende Ende dieser Pavillonfacette ist spitz zusammenlaufend und von der Rondiste weggerichtet. Diese mit der Breitseite an die Rondiste angrenzenden Pavillonfacetten weisen zur Rondistebene in eine Ausführungsform einen Winkel zwischen 39,5° und 41,5°, vorzugsweise zwischen 40,5° und 41° und ganz bevorzugt 40,73° auf. Die Orthogonalprojektion der letzt genannten Pavillonfacetten ergibt den Pavillonwinkel.The pavilion, which is also known as the lower part, has at least 16 pavilion facets, which are guided together in the form of a point or a calette at the opposite end of the panel. In one embodiment, eight pavilion facets have a point located toward the rim, while eight pavilion facets have a broad side adjacent to the rim.

These pavilion facets, which are adjacent to the broadside on the ridge strip, have an angle of between 39.5 ° and 41.5 °, preferably between 40.5 ° and 41 ° and most preferably 40.73 °, relative to the rim plane in one embodiment. The orthogonal projection of the latter pavilion facets gives the pavilion angle.

In einer Ausführungsform der Erfindung beträgt der Winkel zwischen der Rondistenebene und jenen Pavillonfacetten, die eine Spitze aufweisen, die an die Rondiste angrenzt bzw. in Richtung zur Rondiste angeordnet ist, zwischen 35,0° und 37,0° (vorzugsweise zwischen 36,0° und 36,5° und ganz bevorzugt bei 36,28°)).In one embodiment of the invention, the angle between the rondistine plane and those pavilion facets having a peak adjacent to the rondist or towards the rondist is between 35.0 ° and 37.0 ° (preferably between 36.0 ° ° and 36.5 ° and most preferably at 36.28 °)).

Fig. 2 zeigt eine schematische Darstellung zur Erläuterung des Kronenwinkels α, der zwischen der Rondistenebene 7 und der seitlichen Begrenzungslinie 16 der Krone 2 ausgebildet ist, während der Pavillonwinkel β zwischen der seitlichen Begrenzungslinie 17 des Pavillons 3 und der Rondistenebene 7 ausgebildet ist. Fig. 2 shows a schematic illustration for explaining the crown angle α formed between the Rondistenebene 7 and the lateral boundary line 16 of the crown 2, while the pavilion angle β between the lateral boundary line 17 of the pavilion 3 and the Rondistenebene 7 is formed.

Fig. 3a zeigt einen Schmuckstein 1' mit einem Chatonschliff des Standes der Technik (Swarovski A1200). Die in den Schmucksteln eintretenden Lichtstrahlen 13 werden am Pavillon 3' aufgrund der Winkel, mit denen die Pavillonfacetten geschliffen sind, insbesondere wegen des Kronenwinkels und des Pavillonwinkels, nur zum Teil in Betrachtungsrichtung zurückreflektiert. Ein Anteil der Strahlen wird in Form des Strahles 14 zur Seite weg gebrochen oder gestreut. Der Light Retum-Wert ist reduziert Fig. 3a shows a gemstone 1 'with a Chatonschliff of the prior art (Swarovski A1200). The rays of light 13 entering the jewelry are only partly reflected back in the viewing direction on the pavilion 3 'because of the angles with which the pavilion facets are ground, in particular because of the crown angle and the pavilion angle. A portion of the rays is refracted or scattered sideways in the form of the beam 14. The light retum value is reduced

Fig. 3c zeigt dieselbe Darstellung für einen erfindungsgemäßen Schmuckstein 1. Aufgrund der speziellen geometrischen Anordnung der verschiedenen Facetten und des Kronenwinkels α und des Pavillonwinkels β ist die Lichtausbeute deutlich verbessert, da der Großteil der Strahlen im Bereich des Pavillons 3 totalreflektiert wird, sodass nahezu der gesamte Anteil an in die Krone 2 eintretenden Lichtstrahlen 13 nach gegebenenfalls mehrfacher Reflexion in Form von aus der Krone 2 austretenden Lichtstrahlen 15 zum Betrachter zurückreflektiert wird.Due to the special geometric arrangement of the various facets and the crown angle α and the gazebo angle β, the light output is significantly improved, since the majority of the rays in the area of the pavilion 3 is totally reflected, so that almost the entire proportion of entering the crown 2 light rays 13 after optionally multiple reflection in the form of emerging from the crown 2 light rays 15 is reflected back to the viewer.

Die folgende Tabelle zeigt die Unterschiede zum Stand der Technik des bekannten Schmucksteines A1200 der Anmelderin im Verhältnis zu einem Ausführungsbeispiel eines erfindungsgemäßen Schmucksteines "I021".The following table shows the differences to the prior art of the known gemstone A1200 the applicant in relation to an embodiment of a gemstone according to the invention "I021".

Die Figur 4 zeigt die Lage dieses erfindungsgemäßen Schmucksteines I021 im sogenannten Light Retum/Fire-Diagramm. Es ist ersichtlich, dass der erfindungsgemäße Schmuckstein gegenüber dem Stand der Technik A1200 und A1028, einem anderen Stein der Anmelderin gleichzeitig hohe Light Retum-Werte und hohe Fire-Werte aufweist und damit im Hinblick auf die optischen Eigenschaften und den ästhetischen Eindruck dem Stand der Technik überlegen ist.The FIG. 4 shows the location of this gemstone invention I021 in the so-called Light Retum / Fire diagram. It can be seen that the gemstone according to the invention over the prior art A1200 and A1028, another stone of the Applicant simultaneously high light retum values and high Fire values and thus in terms of optical properties and aesthetic appearance of the prior art is superior.

Fig. 5 zeigt in einer schematischen Ansicht eine Messanordnung zur Messung des Light Retum (Lichtausbeute) eines Schmucksteins. Mit einer halbkugelförmigen Beleuchtungsanordnung 16 wird ein sich im Zentrum des Grundkreises 17 der Halbkugel 16 angeordneter Schmuckstein 1 von Lichtstrahlen 18 beleuchtet, sodass die Krone 2 des Schmucksteins 1 mit weißem, diffusem Licht bestrahlt wird, wobei die Lichtstrahlen bis auf einen abgedunkelten Bereich 19 halbkugelförmig auf den Schmuckstein 1 auftreffen und von diesem reflektiert werden. Der Grundkreis 17 ist bis auf Ausnehmung für den Schmuckstein 1 abgedunkelt, sodass von unterhalb des Grundkreises 17 kein Licht auf den Schmuckstein 1 auftrifft. Ebenfalls abgedunkelt ist ein Bereich 19 der Halbkugel 16, die dem Schmuckstein 1 genau gegenüber liegt und einen Öffnungswinkel □ von 46° aufweist. Auch von diesem Bereich kommt kein Licht zum Schmuckstein 1. Der Bereich 19 weist eine Ausnehmung 20 mit einem Öffnungswinkel □ von 3° auf. Diese Ausnehmung 20 dient als enges Messfeld für einen Detektor. Es kann somit oberhalb der Ausnehmung 20 ein Lichtstrom messender Detektor angeordnet sein. Fig. 5 shows a schematic view of a measuring arrangement for measuring the light-return (light output) of a gem. With a hemispherical illumination arrangement 16, a gemstone 1 arranged in the center of the base circle 17 of the hemisphere 16 is illuminated by light rays 18, so that the crown 2 of the gemstone 1 is irradiated with white, diffused light, the light rays being hemispherical except for a darkened region 19 hit the gemstone 1 and be reflected by this. The base circle 17 is darkened to recess for the gemstone 1, so that from below the base circle 17 no light impinges on the gemstone 1. Also darkened is a region 19 of the hemisphere 16, which lies exactly opposite the gemstone 1 and has an opening angle □ of 46 °. Also from this area no light comes to the gemstone 1. The area 19 has a recess 20 with an opening angle □ of 3 °. This recess 20 serves as a narrow measuring field for a detector. It can thus be arranged above the recess 20, a luminous flux measuring detector.

Stattdessen können in einer Computersimulation die jeweiligen lichtspezifischen Werte, wie beispielweise die Helligkeit im Bereich dieser Ausnehmung 20 errechnet werden.Instead, the respective light-specific values, such as, for example, the brightness in the area of this recess 20, can be calculated in a computer simulation.

Die vom Schmuckstein 1 nach oben reflektierte Lichtmenge stellt einen Mittelwert über nahezu alle möglichen Beleuchtungsanordnungen dar und ergibt somit ein quantitatives Maß für den Light Retum (Lichtausbeute) des Schmucksteins 1. Die Reflexionen finden dabei an verschiedenen Facetten statt, sodass Licht direkt beim ersten Auftreffen auf den Schmuckstein, aber auch nach einer mehrerer interner Reflexionen zur Ausnehmung zurückreflektiert wird.The amount of light reflected upwards by the gemstone 1 represents an average over almost all possible illumination arrangements and thus gives a quantitative measure of the light retum of the gemstone 1. The reflections take place on different facets, so that light directly at the first impact the gemstone, but also after one of several internal reflections to the recess is reflected back.

Die Figur 6 zeigt eine Messanordnung für den "Fire"- Wert (Feuer-Wert). Der von einem Halter 20 gehaltene Schmuckstein 1 wird in Richtung von dessen Hauptachse mit einem gerichteten Listen aus der Lichtquelle 21 durch die Öffnung 22 hindurch beleuchtet. Das vom Schmuckstein 1 zurück gestreute Licht wird auf einem Messfeld 24 in Farbe aufgenommen. Die Produktwerte aus Sättigung und Beleuchtungsstärke der im Messfeld (25) erfassten Lichtpunkte werden aufsummiert und geben damit die Maßzahl für das "Fire."The FIG. 6 shows a measuring arrangement for the "Fire" value (fire value). The gemstone 1 held by a holder 20 is illuminated in the direction of its main axis with a directed list from the light source 21 through the opening 22. The light scattered back by the gemstone 1 is recorded in color on a measuring field 24. The product values of saturation and illuminance of the light points recorded in the measuring field (25) are summed up and thus give the measure for the "Fire."

Die Figuren 7a bis 7c zeigen ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Schmucksteines in einer schematischen Seitenansicht, ähnlich der Figur 1a, allerdings ist bei diesem Stein im Gegensatz zum Stein der Figur 1a ein ausgeprägter Umfangsrand 4a (Rondiste) vorgesehen, der in der Draufsicht auf den Schmuckstein kreisförmig um diesen herumläuft.The FIGS. 7a to 7c show a further embodiment of a gemstone according to the invention in a schematic side view, similar to FIG. 1a However, this stone is in contrast to the stone of FIG. 1a a pronounced peripheral edge 4a (Rondiste) is provided, which runs in the plan view of the gemstone circular around this.

Auch ungerade Facettenzahlen sind möglich. Auch müssen die Facettenzahlen zwischen Krone einerseits und Pavillon andererseits nicht übereinstimmen.The invention is of course not limited to the illustrated embodiments, in particular, the number of facets vary, in contrast to the illustrated gemstone, which has both on the panel and the pavilion each 8+ facets, other combination of facets can be used, for example 6 + 6, 10 + 10 or 12 + 12 facets. Even odd facet numbers are possible. Also, the facet numbers between crown on the one hand and pavilion on the other do not have to match.

Beim dargestellten Ausführungsbeispiel hat sowohl die Krone als auch der Pavillon zwei unterschiedliche Schliffwinkel (zweilagige Schliffweise) enthalten. Grundsätzlich sind auch einlagige und mehrlagige Schmucksteine möglich.In the illustrated embodiment, both the crown and the pavilion have two different grinding angles (two-ply cut) included. Basically, one-ply and multi-layered gemstones are possible.

Als bevorzugtes Material wird Glas eingesetzt, vorzugsweise mit einem Brechungsindex zwischen 1,50 und 1,60, und am besten bei 1,55. Es sind aber auch andere Materialien, insbesondere natürliche Steine denkbar und möglich.The preferred material is glass, preferably having a refractive index between 1.50 and 1.60, and most preferably 1.55.
