Do you still wear yours? I wear mine pretty much every day.
I went to a Catholic high school, and everyone has the same design (tradition - same design since before class rings [it was on a pendant]), except for different initials, graduating year, and whether it is yellow or white gold.
When I'm in my hometown (Memphis), strangers occasionally recognize it.
PS - My ring now complements my sorority pin well.
The center has a black triangle with the school's initials in Greek, and the triangle is surrounded by pearls.
