I really must say that even if I wasn't an Alpha Xi I would have to choose my badge. I love the badges that are objects, they just look so unique and delicate. You can tell what organization a girl's from with out a close-up look at the badge. Kappa's badge is my second favorite, with Pi Beta Phi taking a close third!
I have the regular gold Quill right now, but someday I hope to be able to afford the Quill with the row of pearls and the single diamond at the tip. I wish you could still get jeweled silver badges....silver is all I ever wear!
