Taking on the challenge of creating a clean take on vintage design, the Magnum Opus wall light features rows of glass leaves attached to metal stems that curve around a wall plate. The glass leaves sparkle when the light hits them, creating a stunning sculptural light fixture. The white glass contrasts beautifully with the metal in the brass finish, adding an elevated level of texture to the gold sconce while filling the space with a beautiful glow.
