A decorative object including a groove, such as a grooved border or other indicia, with a rounded apex and well-defined sidewalls, formed in the back surface of the object. The back side of the object is painted a first color and the grooved border is painted a second different or contrasting color to give the illusion of a frame made of metal, stone or some other material that is embedded in the object. The illusion of an embedded frame gives the object a three-dimensional visual quality.
