A thermoelectric ornamental assembly for generating thermoelectric energy in a body adornment like a ring. The assembly uses a thermoelectric effect to generate an applied temperature gradient between an inner layer and an outer layer of the ring. The inner layer both receives and transmits a thermal current away from the skin. The outer layer receives the thermal current. Electrons diffuse from the inner layer, which is a warm, excited electron area, to the outer layer, which is a cool, less excited electron area. This gradient creates the thermal current. A thermoelectric layer is sandwiched between the outer and inner layer. The thermoelectric layer includes a substrate portion that supports variably doped semiconductors for creating a difference in conductivity so that the charge carriers can diffuse and create a voltage across the thermoelectric portion. The voltage produces a light visible through a transparent area of the ring.
