A security instrument and method of forming the same, in which the instrument is comprised of a series of layers which overlay one another, and in which at least one of the layers 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, a design emerges at the surface that provides optical variations, depending on the attitude and lighting at which the instrument is viewed.
