The piece of jewellery comprises at least two rings ( 2, 4 ) that can nest inside each other and have different diameters. These rings are assembled to each other so as to pivot relative to each other. The piece of jewellery can thus pass from a configuration wherein the rings are tilted to a configuration wherein they are nesting, such that the surface of the smaller ring ( 2 ) is concealed. The piece of jewellery further comprises indexing means ( 26, 11 c) comprising a pin ( 26 ) secured to one of the rings ( 29 ) and which is arranged for cooperating with the edge ( 30 ) of an elongated aperture ( 11 c) made in another ring ( 4 ), so as to immobilise the rings selectively in a plurality of relative positions.
