Mixed Metals. A double helix of polished brass and nickel rods flute out to cradle bold round bulbs. Kinetic, stately, and glamorous, our Electrum Collection is a future classic. Jonathan believes design is successful if it looks as if it has always existed, as if it was uncovered rather than designed—the Electrum Sconce fits the bill. Electrum is a naturally occurring alloy of gold and silver, and the embodiment of our belief that you should mix your metals with abandon.
