Disclosed is a mobile support mechanism for an object, adapted for being integrated into a wearable piece of jewelry, including a support system bearing an object that is intended to be animated in rotation about a first axis of rotation under the effect of an unbalance within the support system. The support system includes a first frame that is pivotably mounted on a chassis element about the first axis of rotation, and an inner frame that is pivotably mounted in the first frame about a second pivot axis which is substantially orthogonal with respect to the first pivot axis. The object is mounted to a first extremity of a shaft mounted in the inner frame, a second extremity of the shaft being supported by an eccentric element pivotably mounted to a static frame element at a rotation point such that it can freely rotate therearound.

A personal ornament that includes: a base portion that includes a pair of right-and-left base-side engaging ring portions, and fixes and holds a gemstone; and a frame portion that includes a pair of right-and-left frame-side engaging ring portions to be coupled to the base-side engaging ring portions, and that supports the base portion, the base portion and the gemstone being supported to be swingable with respect to the frame portion. The personal ornament also includes a protective member that protects, from an outside, at least the frame-side engaging ring portions, and coupling parts of the base-side engaging ring portions with respect to the frame-side engaging ring portions.

A decorative component includes: a frame fixed to an article; a body-to-be-suspended; and a suspending portion provided to the frame. The suspending portion suspends the body-to-be-suspended such that the body-to-be-suspended is swingable about an imaginary swing axis. The body-to-be-suspended and the suspending portion are held in contact with each other at two contact points located on the imaginary swing axis. The frame covers a part of a periphery of one of the two contact points in one of outer ranges, and covers a part of a periphery of another one of the two contact points in another one of the outer ranges, the parts being not covered with the article.

The personal ornament also includes a protective member that protects, from an outside, at least the frame-side engaging ring portions, and coupling parts of the base-side engaging ring portions with respect to the frame-side engaging ring portions.

An item of jewelry having a base element and at least one gem which is mounted so that it can be moved in the base element such that the gem can move with respect to the base element. The gem is arranged, at least in areas, in a recess of the base element and is secured by at least one retaining element to prevent falling out from the recess. The retaining element extends from the base element slightly over one part of the upper side of the gem such that the center of the upper side is not covered b the retaining element.

Jewelry having a support base and a plurality of decorative elements, each having at least two different decorative zones, each decorative element being fastened in a frame that is secured to a connection member itself pivotally and/or rotatably mounted on the support base. Each decorative zone is oriented differently relative to the frame in such a manner that a different decorative zone is exposed depending on the position of each connection member on the support base, so as to modify the appearance of the jewelry.

A decorative component includes: a frame fixed to an article; a body-to-be-suspended; and a suspending portion provided to the frame. The suspending portion suspends the body-to-be-suspended such that the body-to-be-suspended is swingable about an imaginary swing axis. The body-to-be-suspended and the suspending portion are held in contact with each other at two contact points located on the imaginary swing axis. The frame covers a part of a periphery of one of the two contact points in one of outer ranges, and covers a part of a periphery of another one of the two contact points in another one of the outer ranges, the parts being not covered with the article.

The invention relates to a setting system (1) for a timepiece or piece of jewelry (6). Said system includes: a setting mounting (3);a precious stone (2) mounted in or on the setting mounting (3); anda resilient element (5) attached to the setting mounting (3) so as to flexibly connect the setting mounting (3) to said piece (6). The resilient element (5) has a stiffness between 1.210.sup.5 N/m and 1.4 N/m10.sup.+1, and the combined mass of the setting mounting (3) and the precious stone (2) is between 310.sup.4 g and 410.sup.1 g such that the setting mounting (3) can be oscillated and maintained by movements of the wearer of the piece (6). And when oscillating, the setting mounting (3) oscillates according to an axial and/or radial movement relative to an axis (15) of symmetry at an oscillation frequency between 1 Hz and 30 Hz.

A decorative component includes: a frame fixed to an article; a body-to-be-suspended; and a suspending portion provided to the frame. The suspending portion suspends the body-to-be-suspended such that the body-to-be-suspended is swingable about an imaginary swing axis. The body-to-be-suspended and the suspending portion are held in contact with each other at two contact points located on the imaginary swing axis. The frame covers a part of a periphery of one of the two contact points in one of outer ranges, and covers a part of a periphery of another one of the two contact points in another one of the outer ranges, the parts being not covered with the article.

The present invention provides an automatic wobble jewelry apparatus and setting method thereof, due to arranging two connection grooves in two sides of the body, to placing the connection shaft, where a barrier sidewall is arranged opposite to the connection shaft, to limiting the subpart a wobble range between left and right, and avoid effectively unnecessary wobbles, before avoiding any abrasions caused by the wobbles between them, after a long-term usage, the connection shaft will not get stuck in the connection groove, thus lose the ability of wobbling, instead it may keep the effect of wobbling for a long time, so as to ensure a long-term brilliance effect and extend the service life. The present invention further comprises a cover plate for closing the connection groove and visually making the diamond look larger and more brilliant.
