Abstract
A transparent sphere comprised of a hardened polymeric resin has an insert provided therein. The sphere is prepared such that there is no air gap between the polymeric resin and the insert. The insert is sized to provide an apparent size of the insert which appears to be substantially the same as the diameter of the sphere and to maintain the structural integrity of the sphere under normal conditions of use of the sphere.
