The Square Bell Basic Lamp Shade by Royal Designs, Inc. features elegant, gently flared sides and curved lines in a classic square silhouette—perfect for giving antique or heirloom lamps a fresh, sophisticated update. Its timeless profile adds graceful dimension while working beautifully with both traditional and transitional home décor. Part of our Timeless™ Basic Shade Collection, this shade is handcrafted from premium silk-type shantung fabric in neutral tones. The interior includes an off-white softback lining to produce a warm, diffused glow. (Black fabric shades are lined in gold for added depth and ambiance.) Since 1993, Royal Designs has been proud to offer high-quality shades that blend classic style with exceptional craftsmanship. Measurements are listed as (Top Diameter x Bottom Diameter x Slant Height). Height is measured by slant height from top to bottom of the lampshade’s front face. Please measure your existing shade—a replacement harp may be needed for a proper fit or additional adjustment if changing the height of your shade.
