Phi Beta's badge:
It can be plain gold with engraving on the Beta as shown above. It can also be set with pearls in the Phi (which is more popular with the women).
As far as I know it hasn't changed since its inception. I think it's really cool when people can customize their badges with various stones, etc. (I know I've seen different ones on
LCA badges). I saw a sorority badge that was in white & yellow gold.. I think Gamma Phi Beta? I loved it!! I wear silver and/or white gold most of the time, so I that would be a perfect option for me!
