This lamp shade mimics the shape of a petunia flower and is just as beautiful. The soft scalloped edge at the bottom creates contrast and interest with your lamp base. Made of tailored silk-type shantung fabric with an off-white softback lining (black shades have gold softback lining) to create a warm, soft glow. The Bottom Scalloped Bell Lamp Shade is part of the Royal Designs, Inc. Timeless™ Basic Shade Collection. Royal Designs has been in the lamp shade business since 1993 with our multiple shade lines that exemplify handcrafted quality and value. Height is measured by slant height from top to bottom of the lampshades’ front face. Measurements listed as (TOP x BOTTOM x HEIGHT). Please measure your existing shade--a replacement harp may be needed for a proper fit or additional adjustment if changing height of shade.
