Aqua star cz stainless steel stud
"I love it a lot! It has only fallen out once so far when I was sleeping. Other than that it stays in. I do notice it gets caught on things, but if you notice it and are careful and don't snag away, you'll be fine. It was a smooth process replacing my stud with this one, besides taking my flat back out, that was a bitch. I'm keeping this stud in though until April then I'm putting a hoop in."
