PURPOSE: Regular non-glitter surface is obtained with an initial mark easily, and mass production is available. CONSTITUTION: A mold is composed of a ring mold(10) and a pressing plate(20). A mark of non-glitter is designed in the ring mold, and a glitter surface is wiped out to form a relief of non-glitter. A silicon plate of a thermal-forming silicon is used having thickness of 2-3 mm. The silicon plate is attached to the ring mold and pressed to form a silicon body. The silicon body is attached to a frame. Workpiece is inserted to the frame contacting the silicon body, and diamond particles are injected in a high pressure to obtain non-glitter surface.
