Bumping this, as I have the same question as the OP 8 years later...
I am looking at rings and I can't decide between the Traditional President Ring
http://tiny.cc/0zj2mw or the Square Onyx Square Ring
http://tiny.cc/a1j2mw
Since there is another president ring (with a gavel) that is available, would it be in bad taste to purchase the traditional onyx one if I never served as president (Does Alumnae VP count LOL)? Also, if anyone has pic's of either (trad or square) for size reference, that'd be great. HJGreek doesn't offer measurements!
