Can someone answer a purity ring question? Thanks?

A really good Christian friend and I recently started a book club together, and at one of the meetings we all discussed about whether we wanted to get purity rings. I've always wanted a purity ring, yes way before the 'jonas brothers' were even around (I don't like them at all, I think they are really fake), and apparently a lot of them did too. So we decided that the ones of us that wanted them would all go together to get one. We want to make it a special event where we can try them on, and we are willing for them to be somewhat expensive (like under 200). I've seen a lot of really nice online stores that sell them, but we would like to get them in person. I haven't found an actual store that sells them (that are nice at least), does anyone know of any? I live in San Diego. And for those who love to slander it isn't going to work on me. =) Thank you for all who help! I really appreciate it.
