Crafter? Works Salt Crystal Lamps and Candle Holders are beautifully handcrafted from the purest rock salt in the world and excavated (at 1000 meter deep) from the finest and oldest mines in the foothills of Himalayas. When mining the salt crystals, explosives are strictly prohibited to preserve the structures of the crystals. Lamps are carefully crafted by hand to retain the unique, beautiful and natural shape of the rock. The result is a rare crystal with such beautiful colors ranging from “off-white” to “apricot” and “warm pink”. As the lit bulb or a tea light warms up the lamp, healthful negative ions lift off from the surface and help to cleanse and improve the quality and freshness of the air you breathe.
