Simple and elegant, the River Rock lamp features two stacked ovals turned on a lathe and sanded smooth as river rocks polished by time and water. The walnut wood for our River Rock Lamps is currently sourced from fallen walnut trees from Street Tree Revival in Anaheim, CA. It is hand-turned on a lathe, sanded smooth to the touch, and finished with an environmentally friendly finish. Comes with a cloth-covered wire, in-line switch, harp, and shade. Light socket is a standard, E26 bulb base, typical for table lamps. Please use an LED bulb! The lampshade frame is handmade in Santa Fe Springs, CA and hand-wound with 2mm single-ply cotton cord in natural. The cotton cord is 100 % recycled and OEKA-TEX certified. The lampshade that comes with this lamp is photographed with the brass lamp base. Dimensions of wood base: The diameter of each oval is about 7 1/4" and the height of the wood base is 5". Height with shade is 16 ½". Dimensions of lampshade: 8" diameter x 10" height. Allow me 1-2 weeks to handcraft your lamp. This lamp comes in other wood species!
