I have only one pin right now. ITs the one I was initiatited with: fairly plain with raised hands. It has four pearl points and then a gold "rope" looking engraving in between the pearls. I love it. I still don't have a guard (While I love being in one of the oldest chapters still in existence, I always thought the two letter chapter guards looked the best

)
Someday I would love to get a pin that has pearls all the way around. To me that is the epitome of ADPi pins. I would also like to get a pin with all pearls and then sapphire or aquamarine points.
