I have a few favorites besides of course my beautiful AOII badge!
ZTA! Love this one on HJ Greek!
GPhiB! So pretty with pearls and emeralds!
Alpha Xi Delta...love the emeralds and pearls (I love emeralds in case y'all are wondering!)
Can't leave out KD's gorgeous badge with emerald points!
I know I've seen a KKG key and a Theta badge with emeralds before...just can't find a picture.
But these are all ones I would have to have!!!
