  • Patent number: 4243626
    Abstract: A process of forming a decorative jewelry stone wherein a photographic film image, created by photographing positive artwork and being essentially transparent except for the image thereon, is utilized as the mold for receiving an uncured plastic resin in substantially liquid form. The resin is permitted to cure, the resultant partially formed article with the film portion attached thereto reversed in position such that a second amount of similar resin can be applied thereto to essentially embed the film portion therein. Since the film portion is essentially transparent except for the image thereon, the remaining portions of the film visually merges with the resin segments on either side thereof such that only the image is readily observable.
