A personal ornament manufacturing method comprising: a first step of forming metal flakes through gold beating of metal; a second step of forming the metal flakes obtained in the first step into metal powder; a third step of adding the metal powder obtained in the second step into silicone, and of mixing the metal powder and the silicone with each other through kneading with use of a roll; a fourth step of injecting the silicone obtained in the third step into a die set; and a fifth step of taking out, from the die set in which the silicone is injected in the fourth step, a personal ornament made of the silicone, the die set comprising: a substantially ring-shaped silicone injection space; an injection passage including an injection port located substantially at a vicinity of a center of an inner circle of the substantially ring-shaped silicone injection space, and configured to allow the silicone to be injected through the injection port; a disc flow passage having a substantially disc-like shape expanding from the injection port toward the inner circle, and a thickness smaller than a thickness of the substantially ring-shaped silicone injection space; and a silicone-flow deflection region that is located in the substantially ring-shaped silicone injection space and deflects the silicone, the fourth step including: causing the silicone obtained in the third step to flow into the disc flow passage sequentially through the injection passage and the injection port; causing the silicone to flow into the substantially ring-shaped silicone injection space sequentially through the disc flow passage and across an inner periphery of the substantially ring-shaped silicone injection space; and causing the silicone that has flowed into the substantially ring-shaped silicone injection space to flow in a direction that conforms to a shape of the silicone-flow deflection region. a first step of forming metal flakes through gold beating of metal;
