I still have my high school class ring. In those days all Columbus Public high schools had the same ring, with only the letter representing the school being different.
I wore it until the future Mrs. DA bought an Ohio University class ring for me, which I still wear every day.
I've thought about having DTD letters added to the stone, but never got around to it.
It looks pretty much like the top one below, although in 18k gold. One one side it has my graduation year and the a replica of the bell tower on Cutler Hall at O.U. and on the other side, my degree, BSC, the Great Seal of The State of Ohio and a Bobcat head. Around the stone, it says Ohio University 1804 which is our founding year.
The stone is green for the College of Communication.
