Arrangements and methods for mounting decorative ornaments and fixtures having decorative ornaments are disclosed. The decorative ornaments may be, for example, beads, crystals, or gems. In one aspect, an arrangement is provided including a frame having an aperture and the aperture having an internal surface, and at least one ornament mounting post projecting from the frame, wherein the ornament is retained by the mounting post and the internal surface of the aperture when the ornament is mounted on the mounting post. According to the disclosed method, the ornament is mounted to the post by first deflecting the post to a first position, mounting the ornament, and then deflecting the post to its original position whereby the ornament is retained by the post and the aperture.
