Insignia and symbols Membership pins The essential design of Phi Mu Alpha's official membership pin was adopted at the 1st National Convention in 1901. The design consisted of an upward-pointing equilateral triangle with a gold old-English S on a field of black enamel, surrounded by twelve pearls and six rubies. The pattern of the jeweling was three pearls at each tip, with two rubies separated by one pearl on each side. The design was modified slightly in 1910 by reducing the size of the old-English S to allow room for the Greek letters Φ, Μ, and Α, with Φ in the top corner, Μ in the lower left corner, and Α in the lower right corner. This design remains in use today, though garnets are used instead of rubies. The official membership pin is only worn by initiated members of the fraternity (collegiate, alumni, or honorary). Probationary members are required to wear a special probationary membership pin "at all reasonable times". The design of the probationary membership pin is an upward-pointing equilateral triangle of black enamel surrounded by a border of red enamel, with a thin gold border separating the red and black enamel and another thin gold border around the outside of the pin surrounding the red enamel. Colors The official colors of Phi Mu Alpha are red, black, and gold.
