This is a very pretty chandelier. I returned it because the size was listed incorrectly on the website, and it was too small for the room we ordered it for. The arms are plastic and the "crystals" that I looked at appeared to be a combination of some cut glass and some good-quality plastic; however, I didn't inspect them all thoroughly. Hung high, this chandelier would be quite impressive. It would be perfect for a master bathroom or home office with a high or vaulted ceiling.
