Inspired by the elegant balance of celestial structures, the Sphere & Stem wall lamp is a prime example of carefully curated contrast. A graceful arc of polished brass serves as the "stem," from which two spheres of white marbled stone with veining extend, forming a kind of planetary shapes, culminating in a corresponding metal dome that is the final element of the "stem." This piece transforms standard geometry into a skillful sculptural work, where the warmth of brass meets the cold, timeless texture of stone.
