Taken from the Alpha Phi web site:
Originally there was no standard badge. Until 1906 when the current badge was adopted, each member went to the jeweler of her choice to have her pin designed. Most chose similar designs using the “lazy Phi,” a Phi symbol turned on its side.
Today, special honor badges, replicas of the lazy Phi pin, are worn by international officers, and Educational Leadership Consultants. They are also worn by presidents of collegiate chapters while they serve as president.
