Stone is inspired by the materiality of the same marble used to build the Taj Mahal. The hard, semi-precious stone bears a unique fingerprint - tactile, heavy and long-lasting. Stone is characterized by a solid outer marble ring that appears to be floating around the light source giving out a soft halo effect. Stone Portable Lamp has an integrated touch dimmer and offers up to 9 hours of battery life. A stainless steel silver finish joins the Stone Portable collection, which was driven by demand from the market for a more neutral finish.
