The best salt lamps are made of salt harvested from the Himalayan Mountains. When a light is placed inside the salt lamp, two things happen. The light diffuses through the salt and creates a warm, peaceful glow, heating up the salt so that negative ions are freed. The negative ions clean the air, and help the sense of relaxation we feel when exposed to a gentle rainfall, or a natural water fall. We have many different carved shapes that help to accent the light in playful and beautiful ways.
