Inspired by early 20th Century Theater lighting, these fixtures are of the past in style and materials: built of solid copper and assembled with hand driven rivets, these circular frames feature intricate ornamental copper filigree that is layed over authentic Mica Mineral. In keeping with American Arts and Crafts Era aesthetics, all copper parts are finished with authentic rich natural dark copper patina. Made in Mica Lamp Company's Glendale California shop.
