Jewelry having a support base and a plurality of decorative elements, each having at least two different decorative zones, each decorative element being fastened in a frame that is secured to a connection member itself pivotally and/or rotatably mounted on the support base. Each decorative zone is oriented differently relative to the frame in such a manner that a different decorative zone is exposed depending on the position of each connection member on the support base, so as to modify the appearance of the jewelry.

The invention is directed to a decorative connector for forming a jewelry item, said decorative connector comprising: a decorative member having oppositely located sections, said decorative member comprising a loop at one of said oppositely located sections, said decorative member comprising a decorative body, said loop having a first end fixedly attached to the body of said decorative member, a second end of said loop removably connected to the body of said decorative member to open said loop, the connections between said loop and said body of said decorative member being substantially hidden from view, a passageway through the other of said oppositely located sections of said decorative member, said passageway enabling connecting said decorative connector to a jewelry item.

Implementations of an expandable link are provided. In some implementations, the expandable link comprises a first piece and a second piece moveably connected in an adjustable length configuration.

In some implementations, a method of using the expandable link comprises adjusting the expandable link to increase or reduce the length of the expandable link. In some implementations, a method of using the expandable link comprises connecting one or more of the expandable links to form an adjustable portion of a piece of jewelry or to form a piece of adjustable jewelry.

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.

A jewelry link assembly and a method of assembling jewelry chain links are disclosed. The jewelry link assembly comprises a male member comprising a ball portion having two prongs at opposite ends. The jewelry link assembly comprises a female member having two wings. Each wing comprises a prong receiving section. The ball portion is received between the two wings such that the prongs are made to slide into the prong receiving sections provided at the two wings for interlocking the male and female members. The jewelry link assembly further comprises chain links connected at far ends of the male and female members for forming a two-piece design configuration of the chain links together with the male and female members. The chain links, and the male and female members, are connected alternatively and successively to form a jewelry link assembly.

A watch strap with a plurality of quickly interchangeable, decorative plates attached to express a person's characteristic or style. The watch strap allows for the removal of decorative plates on the watch strap via manipulating a tab attached to the plates. Another variation of the invention is to depress a button, attached to the plate, beneath the watch strap. The plates may also be removably secured via a plurality of screws.

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 bracelet having articulated links, including an articulation between a first link and a second link including a tongue that pivots in an opening between side flanges of this first link together forming a double clevis fitting, wherein, in the articulation, the first link or respectively the second link includes at least one external trunnion or respectively at least one internal trunnion arranged to pivot in an internal half-bearing of the second link, or respectively in an external half-bearing of the first link, the second link or respectively the first link includes at least an upper part and a lower part arranged to enclose and conceal therebetween each external trunnion or respectively each internal trunnion.

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.

Method for making an ornamental article, which envisages a step for arranging, in a 3D printer, a finish plate made of metallic material provided with an inner face and an outer face, and an augmenting step for augmenting, in the 3D printer, an ornamental body formed by a plurality of separate connection elements mechanically engaged with each other, wherein the augmenting step is attained by means of successive welding of metal powder layers, so to fix the plurality of connection elements of the ornamental body to the finish plate. The method further comprises a step for cutting the finish plate into a plurality of separate surface elements adjacent to each other and mechanically connected to the plurality of connection elements.
