A novel method is provided for producing high technology decorative materials that incorporates both computer-aided design and semiconductor processing. The high technology decorative materials thereby produced also make use of microscopic diffraction gratings for generating a dynamic spectral pattern of changing colors when exposed to ambient light such as sunlight, incandescent light, and the like. The decorative materials comprise a semiconductor substrate (10), at least one patterned coating (14) formed on one major surface (12) of the substrate and a transparent layer (28) formed thereover. The patterned coating comprises a material that is capable of being patterned to the dimensions required to diffract incident visible light and includes a series of lines (26) having an arrangement, spacing and width such that incident light will be diffracted in a pleasing pattern. A suitable jewelry mount (44) is attached to individual pieces formed from the substrate.
