• the two passage conduits 22 can be formed in the same plane. In other words, the two passage conduits 22 form an intersection so that they are in communication with one another. The fact of making the two passage conduits 22 in the same plane allows the support mesh 14 to be not very thick because the strands 18 intersect substantially in the same plane. In practice, the strands 18 overlap at the intersection of passage conduits 22 while extending inside the passage conduits 22 which are produced in the same plane.
• a support mesh 14 of reduced thickness makes it possible to guarantee flexibility of the support mesh 14 when it is handled.
• the support mesh 14 as well as the decorative elements are configured to allow elastic deformation of the support mesh 14 when handling the article of jewelry 10.

• passage conduits 22 can extend along different planes spaced from each other.
• the item of jewelry 10 preferably comprises means for fixing the decorative elements 16 to the strands 18 on which they are threaded.
• fixing means at the level of the decorative elements makes it possible to precisely position each decorative element on the support mesh. It is thus possible to vary locally the density of decorative elements on the support mesh, for example when it is desired to obtain a support mesh comprising curvatures. Indeed, a variation in the density of decorative elements associated with a variation in the size of the decorative elements makes it possible to obtain an improved visual effect, in particular by producing a more uniform decoration.
• the fixing means make it possible to fix several strands of said cable or wire so as to be able to form a crossing or a node of the support mesh.
• the fixing of these crossings or nodes makes it possible to maintain a cohesion of the support mesh and to vary the flexibility of this support mesh. Indeed, by locally densifying the number of crossings, it is possible to locally stiffen the support mesh. Conversely, a smaller number of crossings makes it possible to locally soften the support mesh. It is thus possible to adjust the flexibility of the support mesh while retaining good cohesion thereof, in particular by maintaining the three-dimensional profile.
• the fixing means are preferably arranged at a face opposite to a decorative face of the decorative element 16 so as to form a decorative upper portion and a functional lower portion for fixing to the strands 18.

• the decorative elements 16 is equipped with the fixing means.
• the decorative elements 16 devoid of fixing means therefore only have the said at least two passage conduits 22 to allow the passage, or even the crossing, of the strands 18 inside the decorative elements to maintain the cohesion of the support mesh 14.
• the strands 18 can slide inside the decorative elements 16 devoid of fixing means.
• the partial absence of fastening means makes it possible to reduce the mass of the jewelry item 10.

In addition, this bringing into contact makes it easier to assemble the 'article of jewelry 10 by previously defining the relative positions of the decorative elements 16 between them.
• At least two decorative elements 16 adjacent along a strand 18 can be arranged so as to maintain a predetermined clearance or space between said at least two decorative elements 16.
