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 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 flexible jewelry cable includes a plurality of helical links. Each link has a body that extends helically about a central axis of the link. Each link includes a protrusion extending from an inner surface of the body at or near ends of the body. Each protrusion defines a through hole that is coaxially aligned with the body. The body defines a female recess on the inner surface of the body, each recess corresponding to one protrusion. The recesses are at or near the ends of the body. One recess of a first one of the links is configured to receive one protrusion of a second one of the links and align the hole of the received protrusion with the hole of one protrusion of the first link. The cable includes a string extending through the aligned holes of the protrusions of the links.

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.

The present invention relates to jewelry and specifically jewelry with retroreflective inlays. Specifically, the invention relates to a chain link or other jewelry item, with an inlay trough formed in the chain. The inlay trough can be created in a number of ways including casting, CNC milling, photolithography and chemical milling. Once an inlay trough is created, a retroreflective material is embedded in the trough. The retroreflective material which has a bonded top layer of acrylic or polyester is then sealed into the trough with a resin layer that creates a highly reflective, water-resistant, and protective surface. The disclosed invention covers the chain or other jewelry of similar style and the method for producing the jewelry.

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.

A flexible jewelry cable includes a plurality of helical links. Each link has a body that extends helically about a central axis of the link.
