This Himalayan Crystal Salt Lamp is believed to create negatively charged ions in the air. This is a good thing because modern day pollution and electrical equipment create positive ions in the air which are potentially harmful to us and cause air quality in areas affected to deteriorate.
Higher iron, sulphur and magnesium mineral content gives them their darker colour and they have a much softer glow than pink or white salt lamps. Grey rock salt lamps, also sometimes called black salt lamps, are best for bedrooms where you don't want too much light.
By using a Himalayan Crystal Salt Lamp you replace the negatively charged ions in the air which help us to avoid the alleged physical and mental harm that the electric smog creates. Rather than sell them by size we sell them by approximate weight.
Every lamp is completely unique!
