Selenite Lamps are produced from a naturally clear or opaque form of gypsum crystal. Light passes through it easily, creating a warming glow. The selenite, in its natural form, has been hollowed out to create a unique lamp, and the tower effect is achieved by splitting and chipping along natural cleavage surfaces. Each lamp is unique. They can come out in light clear, pink, green, blue, orange shades. And they all come with an attractive rosewood base, an UL approved cords SPT-2 with fixture and switch that can take up to 75W and a standard candelabra based bulb. (Replacement bulbs can be purchased anywhere in the US.)
