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 clement.

An accessory includes an accessory frame body having a pair of bearing recesses positioned at a prescribed spacing, and a decorative member held in a swingable state across the region between the bearing recesses of the accessory frame body, the decorative member extending in the horizontal direction after curving upward at a prescribed location, and having formed at the extended ends, protruding to both sides, swinging arm sections with downwardly-pointing pivoting support shafts, the pivoting support shafts of the swinging arm sections engaging with the bearing recesses formed in the accessory frame body, thereby attaching the decorative member to the accessory frame body in a freely swingable state.

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.

An object, such as a piece of jewelry, which has at least one precious stone supported in a recess of a main body, wherein the recess is bounded at least in some regions by a cover that is transparent at least in some regions and the at least one precious stone moves directly or indirectly on an inner peripheral wall of the recess or along an inner peripheral wall of an insert inserted into the recess.
