Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention relates to a jewellery element, in particular a ring including a precious stone. 
         [0002]    As is known, a conventional ring comprises a ring setting supporting a precious stone or other ornamental element. 
         [0003]    The setting constitutes an integrating portion of the ring-like element which can be engaged on a finger of a hand. 
         [0004]    Also known is the fact that, in the jewellery field, the jewellery element designers are continuously searching novel constructions, that is which are novel from an aesthetic and functional standpoint, thereby, in the time, the jewellery element design patterns have been greatly changed. 
       SUMMARY OF THE INVENTION 
       [0005]    Accordingly, the aim of the present invention is to provide a novel jewellery element construction. 
         [0006]    Within the scope of the above mentioned aim, a main object of the invention is to provide a novel jewellery element setting, for setting a precious stone in a ring or the like. 
         [0007]    Yet another object of the present invention is to provide such a jewellery element specifically designed for greatly improving the brightness characteristics of the precious stone set therein. 
         [0008]    According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a jewellery element construction, in particular a precious stone ring, characterized in that said jewellery element construction comprises magnetic means for causing the jewellery element construction to float with respect to the jewellery element construction base. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0009]    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:

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0016]    With reference to the number references of the above mentioned figures, the jewellery element construction according to the present invention, which has been generally indicated by the reference number  1  and which, in particular, comprises a ring including a diamond, comprises an annular body  2  including a base or bottom  3 , thereon is mounted a setting  4  supporting a diamond, or other precious stone  5 . 
         [0017]    According to the invention, the setting  4  is coupled to the base or bottom  3  by magnetic coupling means. 
         [0018]    More specifically, the magnetic coupling means comprise two magnets, that is a first magnet  6  and a second magnet  7 . 
         [0019]    The first magnet  6  is made rigid with the setting  4 , whereas the second magnet  7  is made rigid with the base  3  through a small plate  8  and a coupling ring element  9 . 
         [0020]    The setting  4  is adapted to slide along upright elements  10  clamped to the base or bottom  3 . 
         [0021]    In the shown embodiment, the upright elements  10  are provided in a number of three, but they may comprise four uprights or any other desired number of uprights. 
         [0022]    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 base or bottom  3 . 
         [0023]    Thus, the setting  4  is adapted to slide between the uprights  10  which are preferably arranged at the apex points of an isosceles triangle, thereby providing a guide for the setting  4 . 
         [0024]    The magnets  6  and  7  are so selected as to repel one another. 
         [0025]    Thus, the setting  4 , and the diamond  5  assembled therein, are urged upward, with the edge portion  11  operating as detent elements. 
         [0026]    The body of the ring  2 , the base  3 , the setting  4 , upright elements  10  and small plate  8  and ring element  9  are preferably made of gold or platinum. 
         [0027]    It has been found that the invention fully achieves the intended aim and objects. 
         [0028]    In fact, the invention provides an actually novel jewellery element construction. 
         [0029]    More specifically, the ring including the construction according to the invention has very pleasant aesthetic properties and is very reliable from a mere functional standpoint. 
         [0030]    In practicing the invention, the used materials, as well as the contingent size and shapes, can be any, depending on requirements.
