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).

The invention relates to an article of jewelry comprising a transparent wall which forms a housing provided to receive a precious or semi-precious stone which is immersed and movable in a substantially transparent liquid in the housing and at least one piece which is movable in the liquid and which has the same refractive index as the liquid, the piece immersed in the liquid being substantially optically indiscernible. The housing is delimited by two walls the internal faces of which are preferably mutually parallel, and the stone is inserted into the piece in order to form a movable decorative element, the piece immersed in the liquid being substantially optically indiscernible and comprising an axis of revolution and two guiding surfaces which are adjacent to the internal faces, respectively, and which allow the movable decorative element to move freely in terms of translation and rotation in the liquid about the axis of revolution inside the housing.

An ornament assembly with a suspension effect, including a base having a bottom frame and a transparent bottom cover, the transparent bottom cover being fixed on the bottom frame; a top frame fit combined with the base to form an integral body, wherein a transparent top cover is fixed on the top frame and the top cover is fit with the transparent bottom cover to form a holding space; a first magnetic member provided on the base; and an ornament, wherein a second magnetic member is provided on the ornament. The ornament is provided in the holding space and magnetic poles of the first magnetic member and the second magnetic member are oppositely arranged such that the ornament is suspended in the holding space under the repulsive force of magnetic forces.
