Abstract: The invention aims to produce an effect of renewing the presentation of decorative objects, making it possible continually to derive benefit from the objects presented. To do this, it is proposed to employ rotating-mount structure combined with an opening in order to produce a mount which reveals different decorational motifs in succession. The rotating-mount structure includes a hoop (1) with central symmetry (.OMEGA.), composed of an external face (F.sub.e) and two lateral faces (F.sub.1) which are symmetric with respect to a mid-plane, the two lateral faces (F.sub.1) forming, as a border, a cylindrical opening. An opening (O) is made in the external face (F.sub.e) in order to reveal a window which extends principally in the mid-plane of the figure and defines a given angular sector (A). Carriers (11 to 14) for the objects (4) to be presented are shaped in such a way as to be housed in the pits of the hoop after juxtaposition via uniting faces (F.sub.a, F.sub.b).
