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 jewelry system with interchangeable decorative segments is provided. The jewelry system includes a plurality of decorative segments, each such segment having a center aperture that extends through the segment along a vertical axis in the center of the segment from a top surface to a bottom surface. The jewelry system also includes a central rod for receiving one or more segments, the rod including a stopper at the lower end to support the received segments and an eyelet at the upper end to receive a chain which when received, prevents the received segments from slipping off the top part of the rod while also facilitating the jewelry to be worn.

An assembly structured to form a customizable, variably configured geometric structure, which includes a plurality of hubs each having an interior chamber and a plurality of housings. Each housing includes an open ended interior channel communicating with the interior chamber of a common hub. A plurality of elastic links are each retained within and extend outwardly from a different one of said interior channels, wherein at least one elastic link of each hub is retained within a housing and connected to one other of said plurality of hubs. A predetermined number of the plurality of hubs may be disposed in interconnected relation to one another to define a closed, continuously configured array of hubs. A plurality of the closed, continuously configured array of hubs may be disposed in interconnected relation to one another to define one of a possible plurality of the customizable, variably configured geometric structures.

Disclosed is a jewellery article including at least one first part having a first cylindrical inner face in which there is provided at least one groove, at least one second part having a second cylindrical inner face provided, in the extension of same, with at least one rim, the at least one rim being arranged facing the at least one groove, and at least one attachment member mechanically secured to the at least one rim of the at least one second part and extending into the at least one groove of the at least one first part; the at least one groove, the at least one rim and the at least one attachment member being configured to allow the at least one first part and the at least one second part to rotate freely with respect to each other.

The jewelry system of the present invention is used for easily layering jewelry by connecting strands of similar types of jewelry, such as necklace strands, into a layered jewelry piece (e.g. multi-strand necklace), and which prevents tangling and provides a distinctive presentation of each layer. The present invention allows for variety in the combining and re-arranging of individual strands in any desired order, by the use of end couplers on the ends of each strand and one or more connector pairs disposed on one or more of strands. This allows for the creation of customized layered jewelry pieces that can be adjusted to suit a variety of styles. The design of the present invention allows for the use of singular strands to form into a layered jewelry piece that is distinctively presented in a symmetrical, cascading arrangement, which moves uniformly as one piece with the weight of gravity, virtually eliminating the risk of tangling. An additional purpose of this system is to have more versatility for the user's jewelry and increase the convenience of wearing fully constructed, customizable, layered jewelry pieces which can be put on and removed as one piece.

There is provided herein a jewelry system comprising a first segment having a shape of a ring, the first segment comprising two coaxially positioned apertures being essentially parallel to the ring's plane; a second segment sized and shaped to fit within the ring of the first segment, wherein the second segment comprises an aperture extending therethrough; and a rod configured to extend through the apertures of the first and second segments, thereby securing the second segment within the ring of the first segment.

A miniaturized coupling for jewelry includes a male coupling and a female coupling, each of which is millimeter-sized or sub-millimeter-sized and each of which is attached to or suited to be attached to a respective jewelry component. The male coupling has a locking member configured to be inserted into the female coupling through an opening into an interior of the female coupling. A resiliently-biased, snap connector located in the interior of the female coupling, so constructed that when the locking member is inserted into the female coupling it initially moves and then is retained by the snap connector. An actuating pin in the female coupling is configured to move the snap connector to release the locking member and thereby disengage the male and female couplings from each other. The actuating pin has an outer surface accessible at an outer surface of the female coupling.
