In Alpha Phi, only pearls, CZ, and diamonds are used, except for 2 variations (that I know of).
In my chapter, the Honor Badge, worn by the chapter President, has turquoise in it.
The Fifty-Year Pin has rubies in it.
Oh wow, in checking the Masters of Design website, I found 2 brand new badges! The 25-year pin, and 75-year pin. When did we get these? I feel so uninformed.
