If you're into really colorful jewelry, and you don't mind the less expensive sort, you may like this store.
It's kind of like a Claire's or Icing, only cheaper, and it's organized according to color -- everything is around $1.99. Â Some of the stuff does look it, but other items are pretty cute and seem like a good ideal. Â It's a very good place to go for teens or younger girls.
Bonus, although the jewelry is super-cheap, not to worry, it's lead-free.
You can also get piercings and they have a good selection of nose, bellybutton, and earrings.
