Setting system for a timepiece or piece of jewelry
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 ); and—a 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 1.2×10 −5 N/m and 1.4 N/m×10 +1 , and the combined mass of the setting mounting ( 3 ) and the precious stone ( 2 ) is between 3×10 −4 g and 4×10 −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.
