<p>A body (1) is machined in order to form: an axial cavity (5) for the stone or other item, said cavity having an edge (1B) that can be pressed over in order to anchor the stone; a lip (1E) that forms an abutment surface (1F) for resting against the surface of the laminar support (3) around a hole (4) formed in said support; adjacent to said lip (1E), a bearing section (9) that widens out and bears against the edge of said hole (4) in the support; and an elastic projection (11, 11A) that is joined to and extends from said section (9) and that can pass into said hole (4) and then re-expand so as to bear against the edge of said hole. <IMAGE></p> |
