Abstract: A decorative medallion consists of two pieces that may be assembled about a mounted fixture. The medallion pieces are decorated with surface ornamentation to add to their visual appeal. A first piece of the medallion includes at a first end an overlapping member whose outline follows prominent features in the surface ornamentation, and at a second end an underledge designed to receive the overlapping member of the second piece. The second piece similarly includes an underledge that is designed to receive the overlapping member of the first piece. The respective overlapping members have recessed edges that are shaped to include one or more alignment features, such as protrusions and concave receiving portions. The underledges are shaped to slideably mate with the corresponding alignment features of the respective overlapping members, and thus, include various corresponding concave receiving portions and protrusions.
