Description

The invention relates to a piece of jewelry with a socket that holds a first stone that has a brilliant cut and second ground stones that are arranged around the first stone and smaller than the first stone holds. A piece of jewelry with the features specified in the preamble of claim 1 is known from WO 2006/03805 A1 as well as from the US 2009/0235689 A1 known.

A similar piece of jewelry is also from the IL 25705 known. By means of the second stones, which are arranged in a ring around the first stone, the visual impression of a diamond is to be created which is larger than the first stone.

From the US 1 351 205 A For example, a piece of jewelery is known which has a centrally arranged first stone and six equally sized second stones which are arranged around the first stone.

From the GB 531 109 A For example, a piece of jewelry is known that has a first stone with a rectangular panel and four stones with a trapezoidal panel. The trapezoidal panels are attached to the four panel facets to create the impression of a single, larger stone. The first stone is framed by two opposing walls. The smaller stones are captured by other walls and at the outer corners mounted brackets.

From the US 2009/0090132 A1 For example, a piece of jewelery is known that has four square-shaped stones arranged in a square and surrounded by 8 stones with a circular circumference. The stones are arranged in a socket, which has for supporting the stones Stotzen, each of which is arranged in a triangular space between two adjacent stones with circular circumference and arranged in a square stones.

Object of the present invention is to show a way how even better the visual impression of a diamond can be produced that is larger than the stones used for the piece of jewelry.

This object is achieved by a piece of jewelry with the features specified in claim 1. Advantageous developments of the invention are the subject of dependent claims.

The second stones of a piece of jewelery according to the invention act on an observer like additional facets of the centrally arranged first stone of the piece of jewelery. This optical effect is based, on the one hand, on the fact that the panels of the second stones, like facets of the first stone, are inclined outwards with respect to the panel of the first stone. On the other hand, between the individual stumps, which are each arranged between two adjacent second stones and the first stone in a piece of jewelery according to the invention, in each case a distance, so that the stones between the stumps can rest against each other or only through a gap whose optical effect negligible is separated from each other. Between the stumps, light can pass through, giving the impression of a large stone.

The stumps of the version of a piece of jewelry according to the invention make it possible to arrange the second stones adjacent to the first stone, so that the boundaries between the individual stones are barely perceptible to an untrained observer.

Preferably, the first stone protrudes with its board beyond the second stones. This means that the panel of the first stone is located at a greater height than the panels of the second stones. In the context of the present invention, the height is the direction perpendicular to the panel of the first stone. The height thus increases in the direction from the top of the first stone to its panel.

By placing the panel of the first stone above the panels of the second stones, one can enhance the impression that the panels of the second stones are facets of the first stone. In this case, it is particularly preferred that the tablet facets of the first stone adjoining the panel are located completely above the second stones. In this way, a particularly large viewing angle can be reached under which the fire of the first stone can be perceived by a viewer.

A further advantageous embodiment of the invention provides that the panels of the second stones are at least partially disposed above the Rundist of the first stone. By having the sheets of the second bricks at least partially at a greater height than the slat of the first brick, it is advantageous to enhance the impression that the sheets of the second bricks are facets of a top of the larger brick. It is particularly advantageous to arrange the panels of the second stones completely above the Rundist of the first stone.

A further advantageous embodiment of the invention provides that the second stones each have a Rundist, which is at least partially below a geometric plane in which the Rundist of the first stone is located, is arranged. For the visual impression of a diamond is the upper part, d. H. the part lying above the Rundiste, decisively. As the crest of the second stones also extends below the plane of the crest of the first stone, the top of the first stone is widened optically not only in diameter but also in height. This contributes particularly to creating the visual impression of a much larger stone. The crest of the second stones is preferably located with the majority of its circumference below the geometric plane of the crest of the first stone. It is advantageous, in particular, when the plane of the round strip of the first stone cuts the round strips of the second stones. In itself, it is also possible to arrange the Rundisten the second stone completely below the level of the Rundist of the first stone.

A further advantageous embodiment of the invention provides that the panels of the second stones with the panel of the first stone each include an angle which is smaller than the upper part angle of the first stone. The top angle of a diamond is the angle enclosed by a line leading from the edge of the board to the girdle and the plane of the girdle. By making the angle between the panels of the second stones and the panel of the first stone smaller than the top angle, the visual impression can be enhanced that the panels of the second stones are facets of the first stone. Preferably, the angle between the panels is of the second stones and the plaque of the first stone between one third and two thirds of the top angle.

Preferably, the panels of the second stones are inclined relative to the panel of the first stone by an angle which deviates at most by 10 °, preferably at most 5 °, in particular at most 3 °, from the angle at which the panel facets of the first stone opposite inclined to it adjacent panel. It is particularly advantageous if the panels of the second stones are inclined at the same angle as the panel facets of the first stone with respect to the panel of the first stone. In this way, the panels of the second stones are particularly advantageous as facets of a larger stone.

The stumps of a piece of jewelry according to the invention can be adapted in their color to the color of the stones. For colorless or nearly colorless stones, metal surfaces with a light, silvery-white luster are particularly advantageous. For example, surfaces of platinum metals are well suited. In particular, rhodinated stubs can hardly be perceived by colorless or almost colorless stones by an untrained observer. For stones with a yellowish hue, such as Fancy Diamonds, it may be advantageous to give the stumps through a gold-bearing surface a yellowish color.

The stumps, sometimes called prongs, for example, may be formed as cylindrical pins. Preferably, however, the stumps have a triangular cross-section. But is particularly advantageous a triangular cross section with three convex curved sides. In this way, the space between two adjacent second stones and the first stone can be filled to a very large extent and so the impression of a single large stone can be further improved.

Preferably, the first stone in a piece of jewelery according to the invention is arranged in the center of a ring formed by eight to sixteen second stones. With a smaller number of second stones are relatively large gaps between two adjacent second stones and the first stone, so that correspondingly larger footprints are needed, larger footprints are visually lighter perceptible and therefore disturb the illusion of a larger stone. If more than sixteen second stones are arranged around the first stone, these second stones are necessarily relatively small, so that the optical magnification of the first stone is correspondingly smaller. Particularly advantageous are 10 to 15, especially 12 to 14 second stones surrounding the first stone.

A further advantageous embodiment of the invention provides that the socket has a central opening, in which the first stone sits, and the central opening annularly surrounding further openings in which the second stones sit has. The openings may be formed as blind holes or as openings of a disc. In this way, the insertion of the stones in the socket can be facilitated.

The first stone has a brilliant cut. The second stones preferably also have a brilliant cut.

a side view too FIG. 1 ;

FIG. 3

an embodiment of a socket for stones of in FIG. 1 shown arrangement.

In the Figures 1 and 2 schematically an arrangement of a first stone 1 and surrounding him second stones 2 is shown, which produces the visual impression of a larger stone. The first and second stones 1, 2 may be in the in FIG. 1 illustrated arrangement with in FIG. 3 presented version are held.

The socket 3 has a central opening for the first stone 1 and the central opening surrounding further openings 4 for the second stone 2. All openings are formed in the illustrated embodiment as openings in a disc.

To hold the stones 1, 2, the version 3 Stotzen 5, which also in FIG. 1 are shown and are each arranged in a triangular space between two adjacent second stones 2 and the first stone 1. The stumps 5 preferably have a triangular cross section with bulged sides. In this way, the spaces between adjacent second stones 2 and the first stone 1 can be filled particularly well.

The socket 3 may have additional positioning elements 6, which engage externally between two adjacent second stones 2.

The stones of the jewelry are preferably diamonds. But you can also use other stones. The stumps 5 are preferably rhodium-plated. The stumps 5 may be made of rhodium-plated white gold, for example. Rhodinated stumps 5 have the advantage that they can be virtually unnoticeable between colorless or largely colorless stones with untrained eye.

The centrally arranged first stone 1 has a brilliant cut. Preferably, this is a modern diamond, which is often referred to as a full diamond. Tolkowski Brillant, Ideal Brilliant, Parker Brilliant, Scandinavian Standard Brilliant or the so-called fine sanding of the practice are for example against the brilliant cuts.

A stone with a modern brilliant cut has an upper part and a lower part with an intervening round list. The top has at least 32 facets in addition to a blackboard. The lower part at least 24 facets. The facets adjacent to the board are called board facets. One main facet stretches between two tablet facets. The Rundiste can connect upper Rundistfacetten, which border on Hauptfacetten.

The second stones 2 may also have a brilliant cut. However, this is not necessary. Because of their smaller size, the second stones 2 may also have fewer facets than required for a modern brilliant cut. The second stones also have a blackboard and a round list.

The panel 2 a of the second block 2 is inclined outward with respect to the panel 1 a of the first block 1. The panels 2a of the second stones 2 may include with the panel 1a of the first stone 1 angle between 10 ° and 30 °, in particular between 15 ° and 25 °. It is preferred that the panels 2a of the second stones 2 with the panel 1 a of the first stone 1 each include an angle which is smaller than the top angle of the first stone 1, preferably between one third and two thirds of the top angle.

The first stone 1 protrudes with his board 1 a on the second stones 2 out. Preferably, most of the height of the top is above the second stones. The panel facets 1 b of the first stone 1 therefore lie completely above the second bricks 2 in the illustrated embodiment.

The panels 2a of the second stones 2 can be arranged completely above the slat of the first stone 1, as shown in FIG FIG. 2 is shown. The panels 2a of the second stones 2 thus extend in the illustrated embodiment between the height of the circular ledge of the first stone 1 and the lower end of the panel facets 1b.

In order to create the impression of a single large stone, it is advantageous if the plane of the circle of the first stone 1 intersects the rounds of the second stone 2. The bottom of the list is in FIG. 2 represented by a line R.

The panels 2 a of the second stones 2 include with the panel 1 a of the first stone and thus also with the R level of the Rundist an angle that matches in the illustrated embodiment with the angle that the panel facets 1 b of the first stone 1 with the Include level R of the list or panel 1 a.

In the illustrated embodiment, fourteen second stones 2 are arranged annularly around the first stone 1. However, it is also readily possible to use a larger or smaller number of second bricks 2. The second stones 2 used for a piece of jewelry are preferably the same, ie have approximately the same size and preferably also the same cut. Preferably, the sizes of the second stones 2 differ by less than 10%, preferably less than 5%, in particular less than 2%. The second stones 2 can touch the first stone 1. But it is also possible that between the second stones 2 and the first stone 1 is a small gap. The width of such a gap should be at most one tenth, preferably at most one twentieth of the diameter of the circular ledge of a second stone 2.
