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 at least one ornament mounting post projecting from the frame, wherein the ornament is retained by the mounting post when the ornament is mounted on the mounting post. 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. In one aspect, ornaments may be mounted to apertures in a frame by means of one or more wires, for example, a wire passing through a plurality of ornaments. The arrangements and methods may be used for ornamental fixtures, for example, chandeliers and lamps.
