There were four other NPC sororities on campus when I rushed, so I'll start with them.
Alpha Phi: This is the crown pearl badge with a CZ, although I'd prefer a diamond to the CZ.
Alpha Chi Omega: (white gold version)
Sigma Kappa: (white gold version)
Kappa Alpha Theta:
(yup, this is AZTheta's new acquisition)
I'll add Pi Phi, as they've colonized at my school since I graduated.
