A customisable item of jewellery comprises a grid (18) with a plurality of openings (20) defining a plurality of distinct closely contiguous adornment locations, and attachment means (30) suitable for releasably retaining a pin of an adornment in each selected one of said plurality of openings; whereby once a plurality of adornments are attached to said attachment means, a cluster of releasable adornments is formed.

The jewelry comprises at least one first holder comprising a horseshoe-shaped part, a lever mounted on a shaft so as to be pivotable relative to the holder between an open position and a closed position, and a second holder bearing a stone, said second holder being intended to be inserted into said part and held in said part by said lever in the closed position.

An apparatus which facilitates an interchangeable look of an item of jewelry by a new process to be able to vary and/or change the complete outlook of a jewelry product; for example by changing the head of a shank to form a new jewelry ring every time the head changes with the help of the innovative mechanism of the present invention. The invention is comprised of a combination of an innovative process, composition of matter and combination device giving infinite options to change an appearance of an item jewelry.

A ring system may include a band; a stationary arm coupled to the band, the stationary am including a first annular end; and a pivotable arm pivotably coupled to the band, the pivotable arm including a second annular end, the pivtotable arm being transitionable between an open position and a closed position relative to the stationary arm, wherein the first and second annular ends form an annulus when the pivotable arm is in the closed position, the annulus being configured to releasably secure a portion of a tiffany setting ring therein.

A cage setting is disclosed and method of retaining an object in a cage setting is disclosed. The cage setting defines a free space therein, configured for retaining an object therein. The cage setting includes a first and second cage end bodies. A number of bar members extend between the first and second end bodies. Each bar member has a first and second end secured the first and second end bodies, respectively. The bar members extend along a periphery that defines the free space. Each adjacent pair of bar members defines a gap having a first gap width that that allows an object to be inserted into the free space. Upon twisting, the first end body with respect to the second end body, the gap is altered to a second gap width, narrower than the first gap width, which captures the object within the free space.
