Abstract:
A jewelry element, in particular a precious stone ring, including a magnetic device to cause the jewelry element to float with respect to the jewelry element base.

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a jewelry element, in particular a ring including a precious stone. 
     As is known, a conventional ring comprises a ring setting supporting a precious stone or other ornamental element. 
     The setting constitutes an integrating portion of the ring-like element which can be engaged on a finger of a hand. 
     Also known is the fact that, in the jewelry field, the jewelry element designers are continuously searching novel constructions, that is which are novel from an aesthetic and functional standpoint, thereby, in the time, the jewelry element design patterns have been greatly changed. 
     SUMMARY OF THE INVENTION 
     Accordingly, the aim of the present invention is to provide a novel precious stone jewelry element construction. 
     Within the scope of the above mentioned aim, a main object of the invention is to provide a novel setting, for setting a precious stone in a ring or the like. 
     According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become apparent hereinafter, are achieved by a jewelry element construction, in particular a precious stone ring, characterized in that said jewelry element construction comprises magnetic means of causing the jewelry element construction to float with respect to the jewelry element construction base. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive, embodiment of the invention, which is illustrated, by way of an indicative, but not limitative, example in the accompanying drawings, where: 
         FIG. 1  is an exploded perspective view of the jewelry element or precious stone ring construction according to the present invention; 
         FIG. 2  is a side elevation view of the jewelry element construction according to the invention; 
         FIG. 3  is a front view of the jewelry element construction according to the invention; 
         FIG. 4  is a perspective view of the jewelry element construction according to the invention; and

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to the number references of the above mentioned figures, the jewelry element construction according to the present invention, or precious stone ring, which has been generally indicated by the reference number  1 , comprises an annular ring body  2  including a top base portion  3 , therefrom extending three upright elements  10  having a substantially triangular cross-section and preferably arranged at the vertex points of an isosceles triangle to define a sliding guide arrangement for a bushing-like setting  4  supporting a diamond, or other precious stone  5 , partially embedded into the top of the bushing setting  4 . 
     According to the invention, the bushing setting  4  is coupled to the base  3  by two magnetic mutually repelling discs, which include a first magnet disc  6  and a second magnet disc  7 . 
     The first magnet disc  6  is made rigid with the bottom portion of the bushing setting  4 , for example by an adhesive connection (not shown), whereas the second magnet disc  7  is made rigid with the flat under face of the base  3 , for example by a further adhesive connection, and through a small plate  8  and a coupling ring element  9 . The second magnet disc is arranged between the small plate  8  and the coupling ring element  9 . 
     Thus, the bushing setting  4  is adapted to slide, under a magnetic repelling force, along straight parallel upright elements  10  vertically extending from said top flat surface of said base  3 . 
     As shown, each upright element  10  comprises, at a free end portion thereof, an inward turned edge  11 , thereby restraining the setting  4  between the edge  11  and the base  3 . 
     The magnets  6  and  7  are so selected as to repel one another. Thus, the bushing setting  4 , and the diamond  5  partially engaged therein, are urged upward, with the edge portion  11  operating as detent elements. 
     The ring body  2 , the base  3 , the bushing setting  4 , upright elements  10  and small plate  8  and ring element  9  are preferably made of gold or platinum. 
     It has been found that the invention fully achieves the intended aim and objects. 
     In fact, the invention has provided an actually novel precious stone ring construction having very pleasant aesthetic properties and novel functional characteristics.
