>Theta Phi Alpha
“The badge is a gold letter “Theta” set with pearls, superimposed upon plain gold letters “Phi” and “Alpha.” The badge of Theta Phi Alpha is worn only by initiated members and is at once a means of identification and a source of pride to the wearer. The Fraternity badge is to be worn over the heart and is always placed above any other piece of jewelry.
The right to wear the Theta Phi Alpha badge is bestowed on each member at Initiation and each member is required to purchase a badge to wear throughout her life. However, should she in any way forfeit the right to wear the badge, it must be relinquished to the Fraternity’s archives.” –ThetaPhiAlpha.org
>Phi Sigma Sigma
“Phi Sigma Sigma’s original badge was the sphinxhead, featuring sapphire eyes on a gold base bearing our Greek letters in blue enamel. In 1951, the Fraternity introduced the sapphire badge, a sphinxhead superimposed on a gold pyramid and three sapphires in each corner. Both badges remain in use today.
Prior to the late 1980s, purchasing badges was optional. Badges were not automatically included in the initiation fee, as they are today. The badges were crafted of 10k gold and often engraved on the back with sisters’ initials and class years. These clues, along with chapter letter guards, can help Phi Sigma Sigma identify who initially owned older badges and when. Since the late 1980s, most badges are gold-plated and do not feature personalized engravings.” –Phisigmasigma,org

“Equilateral triangle with black letters (black onix) and a border with 21 pearls. There is a gold ribbon at the bottom with the motto.” –Dphie.org
>Sigma Delta Tau
“The current badge is a jeweled gold torch. On the front of the torch are the Greek letters ΣΔΤ, with 6 pearls and a diamond. The badge is worn strictly as an emblem of membership and only by initiated members. New Members of Sigma Delta Tau wear a different badge, a gold torch enameled in old blue, representing the colors of the sorority, cafe au lait and old blue. The new member pin is only worn during the new member period.” –Sigma Delta Tau Wikipedia
