An illuminated article of adornment, such as jewelry, having a conductor loop, a magnetically connectable clasp housing a removable battery, and a medallion having internal light emitting diode ("LED"). The clasp consists of two magnetically connectable clasp components, at least one of which is adapted with an interior chamber for containing a battery power source. Each clasp component includes a vertex end connected to an electrical conductor, and a magnetically attractable base. At least one of the clasp components contains a magnet thereby allowing the clasp components to be magnetically connectable in base-to-base relation without requiring precise manual alignment. No further mechanical connection is required. Once connected the clasp completes an electrical circuit resulting in the illumination of an LED electrically connected to the necklace opposite the clasp portion. The LED is preferably connected to or embedded within a crystal to enhance the illumination effect.
