Abstract: The present invention provides an ornament composed of a light transmissive material having a plurality of facets, with a plurality of fine grooves formed on these facets to increase brilliancy, dispersion and scintillation effects and thereby enhance the ornamental appearance.
Abstract: A first film having a low adhesion to a base material (substrate) is deposited on a base material. Pores reaching at least the surface of the base material are then formed through the first film at a high pore density (porosity), for example, according to photolithographic etching technology. Thereafter, a second film having a high adhesion to the base material is formed over the porous first film to fix, or secure, the porous first film to the base material. Recesses may be formed in a surface portion of the base material to further improve the fixation of the porous first film to the base material.
