(1) Further details, advantages and features of the present invention can be gathered from the following description of embodiments with reference to the drawing, in which identical, or rather functionally identical, parts are each denoted by the identical reference sign. In the drawing:

(6) FIG. 5 a simplified schematic sectional view of a gemstone arrangement according to a fifth embodiment of the present invention,

(7) FIG. 6 shows a simplified schematic sectional view of a gemstone arrangement according to a sixth embodiment of the present invention, and

(8) FIG. 7 shows a simplified schematic top view of a jewel, which comprises a gemstone arrangement according to a seventh embodiment of the present invention.

(9) Subsequently, a gemstone arrangement 1 according to a first embodiment of the present invention is described in detail with reference to FIG. 1.

(10) As can be seen from FIG. 1, the gemstone arrangement 1 comprises a first gemstone element 2, a second gemstone element 3 and a decorative element 4. The decorative element 4 is arranged completely in a recess 5 between the first gemstone element 2 and the second gemstone element 3, wherein the decorative element 4 is implanted in the gemstone arrangement 1.

(11) In this case, the recess 5 is formed completely (only) in the second gemstone element 3. However, it is also possible that the recess 5 is formed partly in the first gemstone element 2 and partly in the second gemstone element 3.

(12) In particular, the decorative element 4 is a precious stone or rather a diamond. Other precious stones, gemstones or metal inlays can however also be used as the decorative element 4.

(13) The second gemstone element 3 is directly connected to the first gemstone element 2 by means of a connecting intermediate layer 6. The gemstone elements 2, 3 are also directly connected to one another over an entire surface. The intermediate layer 6 can in particular be formed as an adhesive film, a laminating film, an adhesive or another connecting substance. The intermediate layer 6 is arranged between the first gemstone element 2 and the second gemstone element 3. Thus, a seamless air-tight joint results between the two gemstone elements 2, 3.

(14) Advantageously, an upper portion 40 of the decorative element formed as a precious stone is embedded in the intermediate layer 6. The upper portion 40 of the decorative element 4 preferably comprises a table 43 and/or crown facets 44 of the precious stone or rather corresponds to a crown 45 of the precious stone. The table 43 or the crown facets 44 correspond to a region of the upper portion 40 of the decorative element 4.

(15) Thus, the upper portion 40 of the decorative element 4 is in direct contact with the intermediate layer 6.

(16) Preferably, the recess 5 and the decorative element 4 have complementary shapes at a contact area 15 between the decorative element 4 and the recess 5. In this embodiment, the contact area 15 corresponds to a girdle 41 of the precious stone. The girdle 41 separates the upper portion 40 from a lower portion (pavilion) 42 of the precious stone.

(17) Below the contact area 15, a region 52 of the recess 5 has only vacuum or air. On the other hand, a region 51 of the recess 5 above the contact area 15 is filled in an advantageous manner with material of the intermediate layer 6. The region 52 below the contact area 15 corresponds to a lower region of the recess 5, wherein the region 51 above the contact area corresponds to an upper area of the recess 5. Here, the crown 45 of the gemstone faces toward the upper region 51 of the recess 5 and the pavilion 42 of the gemstone faces toward the lower region 52 of the recess.

(18) Due to this configuration, an overall improved visual appearance of the gemstone arrangement 1 is achieved.

(19) This is firstly because the upper part 45 of the gemstone is not in an air pocket. This means that the crown 45 of the gemstone is not surrounded by air. As a result, fewer reflections occur on the surface of the gemstone, and light falling on the gemstone can enter the gemstone more freely. Furthermore, due to the intermediate layer (lamination compound) which abuts on the crown 45 and which also represents an optical medium, the refractive index and thus also the total reflection angle are reduced compared to the case, in which the crown 45 were surrounded by air. This facilitates the unobstructed exit of the light at the crown 45, which is important for the sparkle of the gemstone.

(20) Secondly, the air located in the lower region 52 of the recess 5 or the vacuum being present allows the light in the lower portion 42 of the gemstone 4 to be totally reflected twice at the interface between the gemstone 4 and the air. This is possible because air or vacuum has a much lower optical density than the gemstone. Because of the large difference between the optical density of air/vacuum and of the gemstone, the total reflection angle, which indicates the angle within which a total reflection of light occurs, is high. This means that in the case of a high angle of total reflection, the intensity of the luminescence or of the sparkle of the gemstone is also high.

(21) The first gemstone element 2 and the second gemstone element 3 are formed from the same gemstone material in this case. For example, the gemstone elements 2, 3 are each formed from topaz, amethyst, citrine or rock crystal.

(22) Furthermore, the first gemstone element 2 is formed in such a way that it has a crown 20 and a girdle 21. In addition, the second gemstone element 3 is designed in such a way that it has a pavilion 30.

(23) For providing the first gemstone element 2 and the second gemstone element 3, a gemstone can be divided. In doing so, the first gemstone can be divided into two parts, wherein the first part comprises, for example, a crown and a girdle and the second part a pavilion of the gemstone. Of these, the first part of the gemstone can be used as the first gemstone element 2 and the second part of the gemstone can be used as the second gemstone element 3. It is also possible that a first gemstone is used for providing the first gemstone element 2 and a second gemstone for providing the second gemstone element 3, each of which is divided into two parts and of which one of the resulting parts is used. This can be advantageous, for example, when a gemstone has an inclusion, so that only a part thereof can be used as the first or the second gemstone element.

(24) After the recess 5 has been made in the second gemstone element 3, the decorative element 4 is inserted into the recess 5 and the two gemstone elements 2, 3 are connected directly to one another by means of the intermediate layer.

(25) Thus, the gemstone arrangement 1, in which a decorative element 4 is embedded, is created. In this case, the gemstone arrangement corresponds to a gemstone, in which a diamond is implanted and which thus has a completely new appearance.

(26) FIG. 2 shows a gemstone arrangement 1 according to a second embodiment.

(27) The gemstone arrangement 1 comprises like that of FIG. 1 a first gemstone element 2, a second gemstone element 3 and a decorative element 4, which is a gemstone, in particular a diamond, and arranged in a recess 5 formed completely in the second gemstone element 3. The first gemstone element 2 is directly connected to the second gemstone element 3 by means of a connecting intermediate layer 6, wherein an upper portion 40 of the decorative element 4 is in direct contact with the intermediate layer 6.

(28) In the second embodiment, the precious stone is arranged in the recess 5 such that the upper part 45 (crown), the girdle 41 and a region of the pavilion 42 of the precious stone 4 project above the plane of the second gemstone element 3. Here, the crown 45, the girdle 41 and the region of the pavilion 42, which is located above the plane of the second gemstone element 3, correspond to the upper portion of the decorative element 4. The contact between the precious stone and the recess 5 thus takes place in the pavilion 42 of the precious stone.

(29) This arrangement of the precious stone in the recess 5 contributes to that the penetration of the intermediate layer 6 into the region 52 of the recess 5 below the contact area 15 between the recess 5 and the gemstone is prevented. Furthermore, the recess 5 and the precious stone can preferably have complementary shapes at the contact area 15. This can be carried out, for example, by chamfering the recess 5. The region 52 of the recess 5 below the contact area 15 corresponds in this embodiment to the complete (free) recess 5, i.e. the region of the recess 5 not occupied by the precious stone.

(30) The gemstone arrangement 1 according to the second embodiment differs from that of the first embodiment also in that the first gemstone element 2 has a first color and the second gemstone element 3 a second color, which are different from each other.

(31) In addition, the gemstone element 2 and the second gemstone element 3 are formed from different gemstone materials, so that the first gemstone element 2 and the second gemstone element 3 have different refractive indices. In particular, the first gemstone element has a refractive index that is smaller than a refractive index of the second gemstone element.

(32) Furthermore, the decorative element 4 formed as a precious stone has per se a third color which differs from the first and the second color. The precious stone also has a refractive index that is higher than the refractive index of the first gemstone element.

(33) Due to the different colors of the gemstone elements 2, 3, the gemstone arrangement 1 can appear with a different color than the first and second color. Furthermore, due to the different colors of the first gemstone element 2 and the decorative element 4 formed as a precious stone, the decorative element 4 is colored with a another color than its original color without artificial processing. Especially when the precious stone is colorless, this appears with the first color of the first gemstone element 2. In other words, the precious stone looks as if it actually had per se the first color of the first gemstone element 2.

(34) In addition, due to the smaller refractive index of the first gemstone element 2 in comparison to the second gemstone element 3, an improved light yield is achieved. The higher refractive index of the decorative element 4 formed as a precious stone in comparison to the first gemstone element 2 has the advantage that the gemstone arrangement 1 shines more.

(35) It becomes apparent from this that optical effects which could never be achieved with a single gemstone (without an embedded gemstone, in this case a precious stone) can be achieved by the design of the gemstone arrangement 1 according to the second embodiment.

(36) For producing the gemstone arrangement 1, a first gemstone and a second gemstone can each be divided into two parts, of which the one part of the first gemstone is used as the first gemstone element 2 and the one part of the second gemstone is used as the second gemstone element 3.

(37) Alternatively, a first gemstone element and a second gemstone element can be connected directly to each other by means of the connecting layer in order to form an arrangement, wherein the arrangement is subsequently cut. Before the connecting step, the first gemstone element and the second gemstone element are elements of gemstones not cut, but sectioned, in particular in block form. It should be noted that the decorative element 4 is inserted into the recess before the connecting step.

(38) In FIG. 3, a gemstone arrangement 1 according to a third embodiment of the present invention is shown.

(39) In contrast to the gemstone arrangements 1 of FIGS. 1 and 2, a decorative element 4 in the form of a metal inlay is provided in the gemstone arrangement 1 of the third embodiment.

(40) The decorative element 4 is also here completely placed in the recess 5 formed in the second gemstone element 3, wherein the first gemstone element 2 and the second gemstone element 3 are directly connected to one another by means of the connecting intermediate layer. However, in comparison to the previous designs, it is not only an upper part of the decorative element 4 that is in direct contact with the intermediate layer 6, but the complete decorative element 4. In other words, the decorative element 4 is completely embedded in the intermediate layer 6 or rather surrounded by the intermediate layer 6.

(41) FIG. 4 shows a gemstone arrangement 1 according to a fourth embodiment of the present invention.

(42) Here, a carrier element 7 in the form of a glass part 70 is arranged between the first gemstone element 2 and the second gemstone element 3. The recess 5 of the gemstone arrangement 1, in which the decorative element 4 is located, is formed in the glass part 70. The glass part 70 is further connected to the first gemstone element 2 and the second gemstone element 3, so that the decorative element 4 is embedded in the gemstone arrangement 1.

(43) In particular, the glass part 70 is connected to the first gemstone element 2 by means of a connecting intermediate layer 8, wherein a region of an upper portion 40 of the decorative element 4 is in direct contact with the intermediate layer 8.

(44) Advantageously, an upper portion 40 of the decorative element 4 formed as a precious stone is embedded in the intermediate layer 8. The upper portion 40 of the decorative element 4 preferably comprises a table 43 and/or crown facets 44 of the precious stone or rather corresponds to a crown 45 of the precious stone. Here, the table 43 or the crown facets 44 correspond to a region of the upper portion 40 of the decorative element 4.

(45) Preferably, the recess 5 and the decorative element 4 have complementary shapes at a contact area 15 between the decorative element 4 and the recess 5. In this embodiment, the contact area 15 corresponds to a girdle 41 of the precious stone. The girdle 41 separates the upper portion 40 from a lower portion (pavilion) 42 of the precious stone.

(46) Below the contact area 15, a region 52 of the recess 5 has only vacuum or air. On the other hand, a region 51 of the recess 5 above the contact area 15 is in an advantageous manner filled with material of the intermediate layer 8. The region 52 below the contact area 15 corresponds to a lower region of the recess 5, wherein the region 51 above the contact area corresponds to an upper region of the recess 5. Here, the crown 45 of the precious stone faces toward the upper region 51 of the recess 5 and the pavilion 42 of the precious stone toward the lower region 52 of the recess.

(47) Furthermore, the glass part 70 is connected to the second gemstone element 3 by means of a further connecting intermediate layer 9.

(48) The intermediate layer 8 and the further connecting intermediate layer 9 can each be formed, in particular, as an adhesive film, a laminating film, an adhesive or another connective substance.

(49) Furthermore, the first gemstone element 2 is formed in such a way that it has a crown 20. Furthermore, the second gemstone element 3 is formed in such a way that it has a pavilion 30. Here, the carrier element 7 corresponds to a girdle 21.

(50) By providing a carrier element 7, in this case a glass part 70, the method for producing the gemstone arrangement 1 is simplified.

(51) In FIG. 5, a gemstone arrangement 1 is presented according to a fifth embodiment of the present invention.

(52) The gemstone arrangement 1 according to the fifth embodiment essentially corresponds to that of FIG. 1.

(53) These differ in that, according to the fifth embodiment, a plurality of decorative elements 4 formed as gemstones is arranged in the gemstone arrangement 1.

(54) To this end, a plurality of recesses 5 formed completely in the second gemstone element 3 is provided, wherein in each recess 5 one decorative element 4 is arranged.

(55) All the decorative elements 4 are formed identically. This means that all the decorative elements 4 are formed from the same material and have the same color, size and shape. In particular, the decorative elements 4 are white (colorless transparent) brilliants. Accordingly, the recesses 5 for receiving the brilliants are formed identically.

(56) A further difference between the gemstone arrangement of FIG. 1 and the gemstone arrangement 1 according to the fifth embodiment is that in the gemstone arrangement 1 according to the fifth embodiment the first gemstone element 2 and the second gemstone element 3 have a smaller refractive index than the refractive index of the brilliants. It should be noted that the first gemstone element 2 and the second gemstone element 3 are composed of the same precious stone material as in the gemstone arrangement 1 of FIG. 1. Furthermore, the first gemstone element 2 and the second gemstone element 3 have a color (the same color) that is different from the “white” (colorless transparent) color of the brilliants. For example, the first gemstone element 2 and the second gemstone element 3 are sapphire parts.

(57) The brilliants are further arranged in a common plane at the same height h, wherein the height h is measured from an upper surface 22 of the gemstone arrangement 1.

(58) The arrangement of each brilliant in the associated recess 5 corresponds to that of the decorative element 4 in the gemstone arrangement 1 of FIG. 1.

(59) The gemstone arrangement 1 is lightened due to the higher refractive index of the brilliants.

(60) When the height h, at which the diamonds are located, is ⅓ of a total height of the gemstone arrangement 1, the color filter effect of sapphire is reduced so that the gemstone arrangement 1 has a new radiant color.

(61) FIG. 6 shows a gemstone arrangement 1 according to a sixth embodiment of the present invention.

(62) The gemstone arrangement 1 according to the sixth embodiment corresponds essentially to that of FIG. 1.

(63) The basic difference lies in that in the gemstone arrangement 1 according to the sixth embodiment, the gemstone formed as a decorative element 4 has a smaller pavilion angle β than the pavilion angle α of the second gemstone element 3 or rather of the gemstone arrangement 1 and that the first gemstone element 2 and the second gemstone element 3 have a common color.

(64) Particularly preferably, the decorative element, the first gemstone element and the second gemstone element are composed of the same gemstone material, so that also the gemstone formed as the decorative element 4 has the same color. In particular, the decorative element, the first gemstone element and the second gemstone element are composed of a gemstone material, the sparkle of which is proportional to the pavilion angle of a gemstone formed from this material.

(65) Due to the steeper pavilion angle β of the embedded gemstone compared to the pavilion a of the gemstone arrangement 1, the light yield, the sparkle and the luminescence of the gemstone arrangement 1 are improved.

(66) In FIG. 7, a jewel 100 that has a gemstone arrangement 1 according to a seventh embodiment and a setting 90 for receiving the gemstone arrangement 1 is shown. The jewel 100 is in this case a pendant for a chain. For this purpose, the setting 90 has a region 91, by way of which the jewel 1 can be affixed to the chain. However, the jewel 100 can also be a ring, a bracelet, an earring or the like.

(67) Here, a plurality of decorative elements 4 is implanted in the gemstone arrangement 1, which are formed as gemstones. The decorative elements 4 are placed in corresponding recesses 5 of the gemstone arrangement 1 in such a way that the decorative elements 4 form the victory symbol. By the targeted positioning of decorative elements 4 within the gemstone arrangement 1, any symbols can be displayed.

(68) It should be noted that, for the sake of illustration, the gemstone arrangements 1 according to the embodiments described above have the shape of a brilliant-cut stone. However, the gemstone arrangement 1 may have the shape of a precious stone with a different cut.

(69) Alongside the written description of the invention documented above, the disclosure of the invention is supplemented by reference hereby being made explicitly to the illustration thereof in FIGS. 1 to 7.
