PURPOSE: Provided is a functional precious metallic ornament, which has increased hardness to inhibit the deformation by external pressure, to prevent the plating layer from peeling off, and to give a favorable effect on human body such as blood purification, cell activation, immunity improvement and nerve tranquilizing action. CONSTITUTION: The functional precious metallic ornament comprises a molding product(10), an electroless copper plating layer(20), a copper sulfate plating layer(30), a first tungsten plating layer(40), a precious metal plating layer(50) plated with Au(gold) and a second tungsten plating layer(60). The molding product(10) is formed by molding a mixture of a negative ion and far-infrared rays radiating mineral and other component or carving the mineral in the desired pattern. The electroless copper plating layer(20) is formed by ultrasonic-washing, dipping into a catalyst solution, washing and then dipping into a mixture of chemical copper A solution and chemical copper B solution. The copper sulfate plating layer(30) is formed by dipping into a mixing solution of copper sulfate, sulfuric acid, a polishing agent and hydrochloric acid. The first and second tungsten plating layer(40,60) comprises the diamond powder.
