The present invention provides for a method of creating a lustrous surface in opaque materials using ridge angles, and valleys of varying depths cut, imprinted or pressed into the opaque material. The combination of the light reflecting ridges, angles to reflect more or less light, and a shadow effect arising from a combination of the valley depths and the angle of the ridges allows one to use light and shadow to create a pattern or series of patterns in the opaque materials. These patterns are created using a process whereby a design is first created, then cut into a master blank using some type of manual or computer-aided method. Next, this pattern is inlaid, pressed, or imprinted into a blank panel composed of the opaque material. In some embodiments, this opaque material is allowed to set, thus creating a finished article of manufacture in the form of a panel.
