I needed replacement jewelry for a couple of cartilage piercings and thought of RebelBod first. They have good quality, affordably priced pieces that are good for daily wear. The cartilage barbells are nice-looking hypoallergenic, standard go-to pieces. The only thing I don't like about them is the round ball backing, but that's personal preference-- i sleep on my side and prefer labret pieces for the flat back because it doesn't irritate as much.
