METHOD FOR THE MANUFACTURING OF GEMSTONES (CRYSTAL IN CRYSTAL)

Description

[0001] In the process of making jewellery with embedded gemstones, the method followed for the attachment of these gemstones on the jewelry, is the following: In the case of a solitaire, a separate seat (cell) is formed in metal mesh, to welcome the gemstone and support it in its lower facets. Then, in order to hold the gemstone in its cell, we fold the sides of the metal cell on the upper face of the gemstone, so it causes the fixation of this gemstone on jewelry.

[0002] Where the composition includes more than one gemstone, depending on the shapes of the gemstones, we create a grid of angular sections for their precise positioning and holding. The cells formed by the vertical sides of the angular cross-sections have exactly the shape of the gemstones, and the horizontal side of the angular cross-sections is used to accommodate and support these gemstones from below. To hold the gemstones through the cells of the grid, notches - protrusions - folds are created in the upper part of the vertical sides of the angular cross-sections, which overlap part of the upper side of gemstones and in this way hold - stabilize them within the metal cells - sockets.

[0003] Disadvantages of the method in paragraphs

[0001] and

[0002] are as follows: The notch - protrusion - folding on the upper surface of the gemstone is always visible and covering part of the gemstone.

[0004] On the lower side of the jewelry, the horizontal sides of the angular cross-sections metal that welcome - base the gemstones are even more visible.

[0005] There is limited possibility to demonstrate the lateral parts of the composition, because these parts are covered by the whole structure that supports - holds the gemstones on the jewelry.

[0006] The result of the above

[0004] ,

[0005] and

[0006] is to conceal most part of the gemstones and thus reduce their radiant effect (shine) and appearance.

[0007] An example of a method of gemstone synthesis is shown in document CN 201 032 881 Y.

[0008] The proposed method of synthesizing composite gemstones is described in the following paragraphs. The numbering used in the description refers to the numbered sections - areas indicated in Figures 1 to 5.

[0009] The composition of the gemstones develops on three levels, from the bottom up. The level (1) is the one that is placed below, the level (3) above and the level (2) between them. The upper and lower levels are transparent or translucent covering the basic composition, that takes part mainly in layer (2). The layer (2) is also transparent or translucent, has a through aperture- opening (4) and is placed on the layer (1). In this way, the through aperture-opening (4) of the level (2) is converted into a socket-seat, based on the apparent surface (6) of level (1) and sides those of the perimeter (5) of the opening (4), fig. 3.

[0010] Here it is noted that the cross-section of the sides of the perimeter (5) can be of any configuration, i.e. straight vertical, straight lines in inclination, curves or any shape, e.g. T-shaped and so on. Four of the infinite possible variations of modulation are given in fig. 5.

[0011] This socket- opening (4) is the one in which the basic composition of gemstones (7) develops, and can have any shape, rectangular, quadratic, triangular, polygonal, circular, ellipsoid, etc.

[0012] The basic composition of gemstones (7) may consist of one to as many gemstones as we wish, each of any shape, which shapes create tessellation, that is, complement each other and thus covering the entire surface (6). The tessellation, depending on the visual - aesthetic result that we wish to achieve, can also be developed in a third axis. This means that the gemstones can complement each other, not only with the aim of covering the surface, but also with the aim of covering volume. They may not always be the same height or they may not be themselves equal in all their extent. In this way, when covering the space caused by the surface (6) and the perimeter (5), fig. 3, the placement of the gemstones that involve the position of the tiles and that will cause the desired composition, will create recesses, gaps and protrusions that the other cooperating tiles will cover or not with their interface. Possibly, again depending on the visual aesthetic result we want to achieve, parts of the space to be filled remain empty.

[0013] The perimeter (5), fig. 3, and the gemstones that will constitute our basic composition (7), fig. 1, for reasons of better assembly - retention can have grooves - slides (8), Fig. 2, on specific sides, depending on our design. The form of the grooves (8) can be of any shape of cross-section, i.e. square (as the shapes that follow) triangular, circular, and so on.

[0014] After covering the opening (4) in level (2), the sealing of the composition is carried out, by placing the level (3) above level (2).

[0015] The total composition forms a single entity composed only of gemstones. Then it is placed in the jewelry with gluing, screws, rivets, driver or any other appropriate - fitting manner.

[0016] The composition method described in paragraphs

[0009] to

[0015] in this case concerns the composition of gemstones.

[0017] The advantages of the proposed method compared to previous ones is described below.

[0018] The upper, lower and lateral parts of the basic composition of gemstones are not covered by material that conceals parts of it, but done within transparent gemstones (levels 1, 2 and 3) that highlight the characteristics and radiant properties of the basic composition of gemstones from all sides of the space. This is in stark contrast to the earlier method and its associated disadvantages, as described in paragraphs

[0004] ,

[0005] ,

[0006] and

[0007] .

[0019] The figures listed below, and used to understand the method, are as follows: Figure 1, where the levels (1) and (3) and (2) in which the composition develops are indicated in an isometric aspect (7) . Figure 2, where the level (2) is developed in isometric aspect to demonstrate an indicative composition (7), the grooves - slides (8) and the opening (4) within which the basic composition develops. Figure 3, where the 2 levels (1) and (2) are developed in isometric view and the surface (6) which is the seat of the basic composition and the perimeter (5) of the opening (4) that delimits the size of the basic composition is demonstrated. Figure 4, showing a side view of the three-level structure and a plan showing the level (2) (the level (3) has been removed). Figure 5 showing 4 different from the infinite possible configurations of the perimeter cross-section (5), as an intersection of C-C in the plan of the previous fig. 4.
