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 disclosure concerns a method for producing an ornamental piece, comprising a step of forming a first, closed ring (32), comprising a step of cutting out a first template comprising a sheet of base material configured to be cut out and pierced, and a step of at least partial winding of the first template with a first set of threads; a step of forming a second, open ring (33), comprising a step of cutting out a second template (43) comprising a sheet of base material configured to be cut out and pierced and a step of partial winding of the second template (43) with a second set of threads (24); a step of intertwining the second ring (33), comprising partial winding of the second template (43) with the first ring (32), comprising at least partial winding of the first template; and a step of closing the second ring (33).

A sectional bra system and accessories includes bra and related jewelry components that can be interconnected in various ways. Jewelry items, such as bra straps, back bands, bridge, and other items, may be formed at least in part from alternating flexible chain segments and rigid connector segments with fasteners configured to attach to standard bra loops. Bra cups for sectional bras include various arrangements of standard bra loops allowing attachment of one or more bra straps, one or more back bands, a bridge, and alternatively other decorative items. Such bra cups may include standard bra loops along all edges. Coordinating jewelry may be made out of the same or similar types of components.

A disclosed bead bracelet loom for making a beaded item includes a clip disposed at one end of a track and configured to hold a portion of a cord. A holder is disposed on the track and spaced apart from the clip. The holder includes a key portion that engages a portion of the track to maintain a position of the holder spaced apart from the clip. The holder including a spring portion that holds a clip configured to hold an end of the cord and maintain a desired tension on the cord member between the clip and the holder.

A jewelry chain having a plurality of links including a plurality of connecting links and one or a plurality of decorative links. Each decorative link comprises alphanumeric character having one or more outline members which becomes part of the chain by connection from at least one connecting link. The connecting link can easily pass through an open section of the outline member to allow rotation and sliding movement in at least two different directions so that the alphanumeric character can provide different appearances when the jewelry chain is worn.

One additional outline member or a portion of an open section of an outline member can include one or more gemstones provided upon a mounting structure therein. The chain can form or be incorporated in necklaces, bracelets or earrings.

A smart ornament chain and a data processing method are disclosed. The smart ornament chain includes an ornament chain body, and further includes illuminants, a collecting module, a driving module and a processing module arranged in the ornament chain body. The collecting module is configured to collect a current dress color of a user and/or a current ambient brightness. The driving module is configured to drive the illuminants to emit light. The processing module is configured to obtain a color and/or brightness of the ornament chain to be adjusted based on the current dress color and/or the current ambient brightness, and is further configured to control the driving module to perform display based on the color and/or brightness of the ornament chain to be adjusted. The ornament chain can adjust its own color and/or brightness automatically based on the current dress color of the user and/or the current ambient brightness.
