An article of chained jewelry may include a pod unit fitting into the body of each pod unit, both stacking up vertically and horizontally. Each pod unit is provided be so that the body of each pod unit is designed to have a protrusion extending out on one side, and an opening on the opposite side of body along an axis. In operation, when one pod unit is place next to another, the protrusion extending from the body mates or connects into the opening of the adjacent pod unit, to form a chain of pod units.

The jewellery 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.

A jewelry item comprises an elastic element extending over the entire length of the item, a plurality of decorative elements threaded one after the other on the elastic element so as to be slidable with respect thereto, and a plurality of connection elements which are each threaded on the elastic element between a pair of adjacent decorative elements and connect the decorative elements to each other, whereby the adjacent decorative elements are displaceable with respect to each other, sliding on the connection element, between a position of minimum relative distance and a position of maximum relative distance. Each connection element is connected to a first decorative element of the pair of adjacent decorative elements by a first bayonet-type engaging device and to a second decorative element of the pair of adjacent decorative elements by a second bayonet-type engaging device.

A link component for a jewellery item includes a hollow body with substantially opposed, spaced side surfaces, one or more junction elements connecting the side surfaces, at least one connecting arm projecting outwardly from one side surface, and a through opening on the opposed side surface. The connecting arm of one link component is designed to be inserted into a corresponding through opening of an adjacent link component. At least one pin with a substantially polyhedral shape and dimensioned smaller than the overall dimensions of such connecting arm is provided on one of the side surfaces, and a corresponding connecting through hole having shape and dimensions substantially equal to those of the pin is on the opposed side surface. The pin of a link component is inserted into a corresponding connecting through hole of an adjacent link component, to prevent relative rotation around the axis of the pin.

The invention provides a flexible ring structure made of loosely-linked prisms, which together define an interior channel. A tensioned spring runs through the length of the channel. The ring, which gives the appearance of a solid and rigid circular structure, can be compressed so as to conform to the cross-section of the finger or hand, and springs back to a circular shape when released. The invention makes it possible to wear an Eternity Ring or a bracelet of smaller diameter than could otherwise be put on the wrist.

Link for an item of jewelry or watch jewelry, comprising an external link (10) comprising at least one opening (11I) in a visible upper surface, characterized in that it comprises an internal frame (20) comprising a receptacle (21) positioned facing the at least one opening (11) in the external link (10), and at least one decorative element (30) visible on top of the external link (10), comprising for fastening purposes a lower extension (32) passing through the at least one opening (11) in the external link (10) and the receptacle (21) in the internal support (20).
