Definitions

• the present invention relates to the field of jewelery, more particularly to a jewelery article comprising an invisible fixing system allowing the assembly of several precious stones.
• This invisible fastening system makes it possible to create, thanks to a special arrangement of several precious stones, an aesthetic aspect which gives the illusion of seeing only one large gemstone when it is observed on the table side.
• Figure 7 represents a gemstone with the indications of the usual terms that are used among others in the rest of this presentation.
• Another device described in the document No. FR 2627359 proposes an invisible crimping having the advantage of not chever (the anchoring is a technical term describing the longitudinal grooves to carve in the breech) that one stone out of two and on the other hand to reduce the appearance of throats side table of the gemstone. Stones hold the unpaved stones in their dwelling. This device does not remove the grooves table side stones but only to mitigate them.
• the purpose of the present invention is to provide an invisible or mysterious crimping system which has the particularity of being able to assemble around a central gemstone several precious stones of predefined shape so as to completely remove the gorges table side gemstones.
• this object is achieved through a jewelery article consisting of a central stone and several peripheral stones arranged around said central stone on a special support.
• This comprises a first concentric ring and secured to a second ring of smaller diameter and height greater than the first ring. Said rings are secured for example by several concurrent branches arranged between the base of the first and the second ring at regular intervals.
• the second ring has a T-shaped shoulder on its upper edge one of whose sides is intended to be driven into a longitudinal groove lying on the entire circumference of the breech of the central stone and the other from its sides is chased in a gorge lying on one of the facets of the peripheral stones.
• the latter are also held firmly in their positions thanks to a groove made on the inner perimeter of the second ring.
• This jewelery article has the advantage of having a continuous fire between the central stone (2) and the peripheral stones (3) due to the absence of grooves usually caused by the systems described in the state of the art.
• this jewelry article has the same aesthetic appearance as ordinary gems of different sizes such as five, ten or fifteen carats while having a much lower cost since the raw material is reduced significantly.
• FIG. 1 shows a perspective view of a jewelery article.
• FIG. 3 shows a top view of the jewelry article.
• FIG. 4 shows a sectional view of the jewelry article along the line A-B of Figure 3.
• FIG. 5a shows a top view of the central stone.

• FIG. 6b represents a front view of FIG. 6a
• FIG. 6c shows a side view of FIG. 6a
• a jewelery item (1) consists of an octagonal diamond (2) and eight small trapezoidal diamonds (3). These diamonds are held together by a special support (4).
• Said support (4) consists of a first ring (5) concentric with a second ring (6) of smaller diameter and greater height than the first ring (5).
• the two rings (5, 6) are secured at their base by several branches (7) concurrent arranged at regular intervals.
• the second ring (6) has a T-shaped shoulder (8) on its upper edge.
• One of the sides of the shoulder (8) is intended to be driven into a longitudinal groove (9) lying on the entire circumference of the cylinder head (10) of the octagonal diamond (2).
• the other side of the shoulder (8) is driven into a groove (11) on one of the facets close to the edge of each small diamond (3). It is also held firmly in its position thanks to a groove (12) made on the inner perimeter of the first ring (5).
• the arrangement of each small diamond (3) next to each other around the central stone (2) through the support (4) can reproduce continuously the crown of a diamond brilliant cut.
• Said eight small diamonds (3) have been cut so that the length of the edge of one of their sides is identical to the length of the edge of one of the facets (14) on the crown of the octagonal diamond ( 2).
• the height and the diameter of the first ring (5) have been determined so as to create an angle of incidence of the table (13) of the eight small diamonds (3) corresponding to the angle of incidence of one of the facets (14) the crown of the octagonal diamond (2).
• this crimping system makes it possible to transform an authentic small "size 16/16" diamond into a larger “brilliant cut” diamond when it is observed from above while using approximately one-tenth of the raw material necessary for the realization of an authentic diamond of this type.
• the periphery of the cylinder (5) is continuous and opaque thus masking the fixing device while the cylinder (6) may have discontinuities.
• the embodiment is in no way limiting and therefore instead of the embodiment described above, the diamonds can be replaced by any other type of precious or semi-precious stones in order to be able to offer articles. jewelery exhibiting various aesthetic aspects.
• the item of jewelry (1) can be mounted on a ring where a pendant.
• the invention is not limited to rings, but is applicable to all kinds of jewelry items such as earrings, necklaces, bracelets.
• the invention also relates to a decorative article comprising the article of jewelry of the present invention.
