  • Patent number: 6003228
    Abstract: The invention is a method for making a reverse intaglio decorative or jewelry item and the product made by the method. Any suitable graphical image is scanned into digital memory. The image is changed from two-dimensional to three-dimensional by adding contour to the original image using appropriate graphics software. The contour is scaled for the production of first and second slightly different sizes. Both sized images are converted to a computer numeric control dataset for controlling a milling machine, which cuts the first contour into the underside of a cabochon of stone or crystal and the second contour into a die stamp tool. An insert is die-stamped into metal, said insert having a convex surface that matches the contour of the first contour milled into the cabochon. The insert is painted and mounted into the cabochon to form the reverse intaglio. Suitable inserts may also be produced by molding and casting rather than machining methods.
