A die and a method for forming a die to produce optically varying effects in a light reflective surface. A design generally formed as a plurality of parallel grooves of varying widths and depths are engraved in a soft metal foil adhered to a substrate. A hard metal coating is formed on the engraved soft metal foil in a metal plating bath. The hard metal coating, removed from the soft metal foil provides a die formed as a mirror image of the grooves engraved in the soft metal foil. The die is used to deform a reflective surface such that the surface produces optically varying effects. A die formed in the same manner with further processing is used to both deform a reflective surface and hot stamp it to a substrate.
