Add a warm glow to your room with this Himalayan Salt Crystal Diffuser with Light. Sourced from the salt mines of the punjab region of Pakistan, near the foot of the Himalayas, the salt crystals have a lovely reddish hue when lit. Some believe that with the gentle heat of the lamp, the salt emits negative ions which purify the air and are beneficial to health. Either way, we just love the look and their soft, warm glow.
