A personal ornament which has an appearance of nickel tone or black nickel tone and assumes no magnetism is disclosed. In one embodiment of the personal ornament, a chromate layer (11) is formed on a surface of a substrate (10) made of pure zinc and a clear coating layer (12) of brown color is superposed thereon. In another embodiment of the personal ornament, a Cu layer (21), a pure Zn layer (22), a chromate layer (23), and a clear coating layer (24) of brown color are sequentially superposed in the order mentioned on a surface of a substrate (20) made substantially of zinc. Further, in a personal ornament having an appearance of black nickel tone, a Cu layer (31), a Zn-Cu alloy layer (32), a brass activator conversion coating (dyed black) layer (33), and a clear coating layer (34) of brown to black color are sequentially superposed in the order mentioned on a surface of a substrate (30) made substantially of zinc.
