Specifically, the ornamental article 1 of the present invention is of extendable type and hence is configured to automatically fit the form of the wrist or finger.

The ornamental article 1 comprises an open annular element 2 having two ends 2a. In particular, the ends 2a of the annular element 2 can be moved toward and away from each other along a circumferential direction C-C.

The annular element 2 is elastically deformable in a reversible manner along the circumferential direction C-C. Therefore, the annular element 2 is a mechanical member that elastically deformed under load and return to initial position when the load is removed. Specifically, when the ends 2a of the annular element 2 are moved away from each other along the circumferential direction C-C, they tend to spontaneously move toward the initial position.

The annular element 2 is preferably made of precious metals such as gold, steel or silver. Nevertheless, in alternative embodiments, the annular element may be made of any material that can be elastically deformed in a reversible manner.

The ornamental article 1 comprises a guide element 3 that is coupled to at least a portion of the annular element 2. In detail, as shown in FIGS. 1 and 2, the guide element 3 is configured to be coupled with the portions of the annular element 2 at each end 2a thereof.

The guide element 3 is configured to allow the ends 2a of the annular element 2 to slide therein. More in detail, the ends 2a of the annular element 2 slide in the guide element along the circumferential direction C-C and move toward or away from each other to adapt the ornamental article 1 to the form of the wrist or finger.

The guide element 3 comprises a limit stop member 4 configured to limit the movement of the ends 2a toward each other along the circumferential direction C-C. The limit stop member 4 is designed to prevent the two ends 2a from contacting each other, thereby avoiding the risk that they might get stuck with each other and affect proper operation of the ornamental article 1.

The ends 2a of the annular element 2 move away from each other by sliding in the guide element 3 to switch the annular element 2 between a first configuration and a second configuration. In the first configuration, as shown in FIGS. 1 and 2, the ends 2a of the annular element 2 press from opposite sides against the limit stop member 4; conversely, in the second configuration, as shown in FIGS. 3 and 4, the ends 2a of the annular element 2 are spaced apart by the limit stop member 4.

Preferably, the guide element 3 extends along, the circumferential direction C-C between two opposite guide ends 3a. The limit stop member 4 is rigidly linked to the guide element 3 and is interposed between the aforementioned guide ends 3a. In a preferred embodiment, the limit stop member 4 is centered along the circumferential direction C-C between the two guide ends 3a.
