Wow. I learned something about my own CoA from this thread! (That Emily Helen Butterfield helped design our CoA).
Phi Beta's Coat of Arms:

Higher res of Phi Beta CoA)
Note the difference between the gold & green laurel leaves. You will see our CoA with both. Until recently it was this design:
And our original CoA (from a bad scan from an old magazine) which is quite different.

The things I can tell you about the CoA are that our official flower is the American Beauty rose, which is pictured, and that the banner at the bottom is our motto in Greek "To Be Rather Than To Seem To Be".
Another official symbol that is fairly recent to us is our Allied Arts Design.
It's pretty obvious that it combines symbols of the arts we represent (nothing secret about this one!) music, art, dance, visual arts, etc. I've been told there's supposed to be a pen for writing under the dancer's feet, but I've never actually seen that. It's a popular jewelry piece for our members. (More bad photos!)
