description Core, designed by Christian Lava, is reminiscent of the natural energy at the heart of our world. Like bright lava seeping through the earth’s crust, vibrant spheres of faceted glass break through the iron surface of this pendant. Forcing light to pass through this metal structure results in a powerful, vibrant exchange of forces light and shadow erupt across the room, as the led light pours through, as the light itself emits an organic radiance.
