Notes:William Claude Harper (born 1944, Bucyrus, Ohio) is a seminal figure in American studio jewelry whose work bridges fine art, craft, and mythic narrative. Now based in New York, Harper is celebrated for his masterful reinvention of the cloisonné-enamel technique, using gold and silver wires as expressive drawing elements within richly colored enamel fields. His intricate, sculptural pieces combine precious metals, enamels, gemstones, and unconventional materials such as feathers and animal teeth to create wearable objects imbued with ritual and storytelling. Represented in major museum collections including the Metropolitan Museum of Art and the Victoria & Albert Museum, Harper has been a leading voice in the American studio-jewelry movement for more than five decades, crafting works that are as much meditations on beauty and transformation as they are adornments.
Pendant 4 x 3 1/8 inches.
