Abstract: Ornamental assemblies are formed by snap-type action securing elements formed respectively on ornamental bases and caps so that a number of different caps can be attached to a single base to fabricate a number of different assemblies. The assembly has a hollow cap element having top and side walls. The side walls have inner and outer surfaces-which co-terminate at an edge lip. A collar is attached about the inner surface of the side walls of said cap element at the edge lip. A base element is attached to the collar by means for snapping the base element and the collar together. The items of ornamentation may be buttons, buckles or items of jewelry.
