A wearable decorative element comprising at least one ring-shaped elastic member, supporting a plurality of female elements, each of the female elements comprises a hollow body extended between a first and second through opening obtained between two opposite lateral walls for the passage and sliding of said elastic member, a plurality of hollow male elements arranged on the elastic member alternating with the female elements and adapted to allow the passage and sliding of the elastic member therein, each of the male elements fitting in a sliding manner at least partly inside one of either the first through opening or the second through opening of one of the adjacent female elements, each of the male elements comprises at least two toothed elements configured, to fit inside the hollow body to limit the mutual sliding between the female elements on the male elements at a predefined maximum distance between the adjacent female elements.

The bracelet has more than one main platform fixed on one another so as to form a ring, more than one main assembly item enabling affixation of each main platform onto one another and a decorative part installed on each main platform in a removable manner without disturbing the ring-shaped form of the bracelet.

A method of making tennis bracelets includes coupling together collet elements (2) in a repetitive series, wherein an L-shaped lateral appendage (3) of a collet element is inserted into a through hole (6) of an immediately adjacent collet element and then bent against a face (7) of the collet element to which it belongs. The collet elements are inserted according to the repetitive series into an assembly template (10) implemented as a self-supporting unit provided with fasteners (16) for fastening the unit to first and second carriage supports (22, 36) of first and second machines (18, 19), which cause the assembly template to translate under a die block (26) of a press device (24) of the first machine. The lateral appendages (3) of the collet elements are bent in succession under a laser welding head (38) of the second machine, for welding the appendages (3) to their respective collet elements.

A wearable decorative element comprises a ring-shaped elastic member (EM), supporting a plurality of female elements (FEs), wherein each FEs comprises a hollow body extended between a first and second through opening (TO) obtained between two lateral walls opposite each other for passage and sliding of the EM, a plurality of male elements (MEs) adapted to allow passage and sliding of the EM therein, each of the MEs inserting in a sliding manner partly inside one of the first TO and the second TO of one of the adjacent FEs to vary the mutual distance between the FEs along a direction of sliding, and a block element associated with one of either the FE or the male element transversely with respect to the direction of sliding to limit the mutual sliding between the FEs on the MEs and to cover the EM when distance between the adjacent FEs is maximum.

An extensible jewelry item includes an annular element formed by a plurality of links and an internal titanium or stainless steel spring is mounted to extend each link. Each link has on each side an external female element and an internal male element. The female elements are micro-slots in the extended sections of each links. The male elements are internal micro-posts that extend through the female's slots to restrict the movement of the female elements of the link adjacent thereto away from each other. The micro-size of posts and slots enables the mechanism to be applied to links as small as 2.0 mm×2.0 mm×2.0 mm; therefore, also ideal for fine jewelry rings. In the elliptical version of the extensible jewelry item, the adjacent surfaces of each link are designed with individual specific taper angles; thus, when assembled, the links form an elliptical shape. In the elliptical shape, each link is numbered, and is placed in specific position. In the round version of the extensible jewelry item, the taper angles of the adjacent surfaces are all the same; therefore, the links are not numbered and is not relevant where they'll be placed.

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.

A link component (10A-10D) is described for assembling a jewelery item featuring a chain-link structure. Each link component consists of an internally hollow body comprising a pair of side surfaces (12, 14) substantially opposed to and spaced from each other, one or more junction elements (28, 30) for connecting the side surfaces, at least one connecting arm (16; 18), which projects outwards from one of the side surfaces, and at least one through opening (20; 22), obtained on the opposed side surface. The connecting arm of a first link component is designed to be inserted into a corresponding through opening of a second adjacent link component to connect these two link components. At least one pin (24) having a substantially polyhedral shape and having overall dimensions smaller than the overall dimensions of such connecting arm is provided on one of the side surfaces, in addition to the connecting arm, whereas a corresponding connecting through hole (26) having shape and dimensions substantially equal to those of the pin is provided on the opposed side surface. The pin of a link component is designed to be inserted into a corresponding connecting through hole of an adjacent link component, so as to prevent a relative movement of rotation around the axis of the pin, between such adjacent link components in an assembled configuration of a jewelery item.

Link for an item of jewelry or watch jewelry, comprising an external link (10) comprising at least one opening (111) 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).

An article of 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.

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.
