A security instrument (10) and method of forming the same, in which the instrument is comprised of a series of layers (21,23,25)which overlay one another, and in which at least one of the layers (23) has a pattern imprinted thereon in a predetermined location, with pearlescent materials of varying colors and hues. When the layers are bonded together on a base member (21), a design emerges at the surface that provides optical variations, depending on the attitude and lighting at which the instrument is viewed.
