An interchangeable decorative element system includes a decorative portion and a base portion. The decorative portion holds a decorative element and includes a plurality of studs. The base portion has a plurality of tracks, each of which has a guiding portion configured to be engaged by a respective stud of the decorative portion. In a first configuration, the decorative portion is aligned with the base portion, such that each of the decorative portion is received within the first end of the guiding portion of a respective track of the base portion. Rotation of the decorative portion in a first direction relative to the base portion causes each stud received within the first end of the guiding portion of each track to move along the guiding portion until the stud engages the respective catch, thereby transitioning the interchangeable decorative element system from the first position to a second, assembled position.

A movable decorative element, intended to be freely rotated and translated between two walls (5, 6) whose inner faces are parallel to each other, at least one of which is transparent, includes a precious or semi-precious stone (2) mounted in a socket (1). The socket (1) includes a closed bottom (4) whose outer face is bulged to promote the rotation of the decorative element when this bulged outer face (7) is applied against the inner face of one of said walls, and an open outer (7) opposite to the bottom (4) which is flush with or which protrudes relative to the stone (2) to form a bearing surface against the other of said walls (5, 6) when the decorative element is disposed between the two walls. The precious or semi-precious stone (2) is held in its socket (1) by a plurality of arms (3) which extend above a body (8) of the socket (1) and which crimp the stone (2), these arms (3) leaving, therebetween and above the body (8) of the socket (1), lateral openings (9) letting appear the flanks of the stone (2) between the arms (3), and said bearing surface is constituted by the free ends of said arms (3) in the form of separate contact areas spaced from each other around the periphery of the open outer face (7) of the socket (1).

A jewelry item comprises a ring-shaped spring; a ring-shaped chain comprising a plurality of chain links wherein each chain link is slidably attached to the support element; each chain link comprises a plate having a first surface facing the spring and a second surface opposite to the first surface; a seat and a hook opposite to each other, the hook is inserted into a seat of a subsequent chain link so as to lock the chain links to each other while allowing the chain links to reversibly slide from a contact position to a distanced position with respect to each other.

Provided is a 360-degree rotatable accessory. The 360 degree rotatable accessory can be used for various purposes such as a decoration of a bag, or a finger ring, a necklace, a bracelet, and an earring, can be rotated a predetermined angle, that is, 360 degrees around a coupling portion, that is, a body, and can be transformed into various shapes because it can be rotated a desired angle and firmly maintained at the angle, thereby having high commercial value and quality.

The present application discloses a splicing structure that can be broadly apply to toy, tool, furniture, handicrafts, jewelry or other fields. The splicing structure comprises a splicing block capable to detachably spliced with one another, said splicing block comprises a splicing hole and a splicing column. The splicing structure also comprises a plug piece having an insertion rod, said insertion rod having protrusions along its periphery; a receptacle having an insertion hole, wherein outer diameter of the protrusions, inner diameter of the insertion hole and outer diameter of the insertion rod decrease. The plug piece is mounted between the splicing column and the splicing hole, said receptacle is mounted within inner hole of the splicing column; when two splicing blocks are spliced through inserting a second splicing block into a first splicing block, insertion rod of the first splicing block is inserted into the insertion hole of the second splicing block by interference fit and the two splicing blocks are firmly spliced together by snap fit connection between the protrusions of the first splicing block and the insertion hole of the second splicing block.
