An extensible ornamental item comprising an annular element formed by a plurality of meshes and an elastic ring mounted passing through each mesh, each mesh having a female element and a male element constrained in a mutually movable manner to the male element and to the female element, respectively, of the two adjacent meshes, each male element comprising a tubular body provided with flaps comprising a slot, each female element comprising a central body, a circular hole, two circular openings and two pairs of pins. Each pin is adapted to engage in the respective slot of the male element.

A method for making a bracelet provided with an electronic component insert, the method includes fabricating a basic, flexible support for an insert in the form of a band, making conductive paths on the flexible support or in the flexible support, disposing on the flexible support various electronic components connected to the conductive paths, and coating the electronic components disposed on the flexible support with a transparent or opaque protective layer to finish the insert of the bracelet.

The jewelry item comprises an elastic element, which extends along an extension direction of the item through the entire length of the item, and a plurality of ornamental elements, which are threaded one after the other on the elastic element so as to be slidable relative to the elastic element and are non-releasably connected in twos to one another. Each ornamental element comprises a hollow body having a pair of longitudinally opposite first faces, namely a right-hand face and a left-hand face, respectively, and a pair of radially opposite second faces, namely an inner face and an outer face, respectively. The right-hand face of each ornamental element has a through opening communicating with an inner cavity of the ornamental element.

An extendable ornamental article comprises an open annular element having two ends that can be moved toward and away from each other along a circumferential direction; a guide element coupled to the annular element and configured to allow the ends to slide therein; a limit stop member configured to limit the movement of the two ends toward each other along the circumferential direction; the ornamental article is characterized in that the annular element can be elastically deformed in a reversible manner along the circumferential direction.
