This Tiffany style lamp is hand-crafted using the same techniques that were developed by Louis Comfort Tiffany in the early 20th century. Each piece of glass is hand cut to the perfect shape and size, wrapped in copper foil, and soldered together to create a truly unique piece of art. Made with 128 pieces of hand-cut stained glass and 20 jewels. Requires one 60W E26 medium base type A bulb (Not Included). Our lamps are fully compatible with CFL and LED bulbs. This lamp must be hardwired. Please consult a professional electrician for installation. Shade colors will appear darker and less vibrant when not illuminated. The handcrafted nature of this product creates variations in color, size and design. If buying two of the same item, slight differences should be expected. This stained-glass product has been protected with mineral oil as part of the finishing process. Please use a soft dry cloth to remove any excess oil.
