Former U.S. Senator and jeweler Ben Nighthorse Campbell has created a new design to benefit the Smithsonian`s National Museum of the American Indian. The silver and turquoise necklace is in the Naja pendant shape, which was originally a Moorish talisman. Campbell donated the original which has one side decorated with petroglyphs and the other with celestial symbols and Smithsonian has created the copies. The pendant costs $550 and is available on the museum website.
