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.
