These custom pendants are delightful. I'm certain they will make a lasting impression on viewers for years to come. All the exposed hardware (minus a single quick-link) is made from 100% solid brass, from the cage and cast arms to the hand-bent scrolls and decorative rosettes-everything is 100% solid brass. The diffuser is made of high-impact Crystal Idalight, the artisans' choice for beauty, safety and durability. The transparent Idalight allows the observer to see the beautiful, brass scroll arms arranged in a 3-tier formation supporting 15 individual 60-watt bulbs. The diffuser is scratch resistant and shatter proof, protecting against accidental damage during maintenance, natural occurrences or intrusion.
