A lot of piercers use either implant grade surgical steel or titanium jewelry. My tragus piercing has the surgical steel and it has never been a problem. It healed much more quickly than any of my lobe or cartilage piercings that were pierced with gold. Most people don't react to surgical steel or titanium. I know that surgical steel doesn't sound really pretty but it has a nice dark grey finish and you can choose the ball for your captive bead ring or barbell. I like hematite. : )

Good luck--I love tragus piercings. I'm saving to get my other one done.
