Abstract
A jewelry bead has a rigid hollow body with an exterior wall of a first metal and a covering of a second metal whose color is different from that of the first metal. The covering overlies one or more selected areas of the wall so as to define an all-metal substantially level color pattern on the bead. A method of making the jewelry bead is also disclosed.
