This lamp is made of salt crystals, from deep within the Himalayan Mountains, home to the world's purest and most colorful salt. The lamp is simply sophisticated! It is made of wire intertwined to form a basket and a light bulb sits in the midst of natural salt crystal chunks. It is almost maintenance free and is very easy to clean. Just empty the basket and wipe each salt crystal chunk with a damp sponge then dry off with a paper towel. You can change the color of the bulb to give a different hue to the lighting area. You can keep the lamp lit for as long as you like and the longer you keep it on, the better the emission of negative ions. Place this lamp in your child's room and watch him fall asleep with gentle ease or put it next to your computer and feel your stress dissipate as the negative ions counteract the electromagnetic fields bouncing off the computer. You can put it in your TV room, or your office. It really doesn't matter which room you choose, it is totally up to you where you want to place this unique gift of nature.
